### Description
Design document: https://cwiki.apache.org/confluence/display/CLOUDSTACK/%5BDRAFT%5D+Minimal+changes+to+allow+new+dynamic+hypervisor+type%3A+Custom+Hypervisor
This PR introduces the minimal changes to add a new hypervisor type (internally named Custom in the codebase, and configurable display name), allowing to write an external hypervisor plugin as a Custom Hypervisor to CloudStack
The custom hypervisor name is set by the setting: 'hypervisor.custom.display.name'. The new hypervisor type does not affect the behaviour of any CloudStack operation, it simply introduces a new hypervisor type into the system.
CloudStack does not have any means to dynamically add new hypervisor types. The hypervisor types are internally preset by an enum defined within the CloudStack codebase and unless a new version supports a new hypervisor it is not possible to add a host of a hypervisor that is not in part of the enum. It is possible to implement minimal changes in CloudStack to support a new hypervisor plugin that may be developed privately
This PR is an initial work on allowing new dynamic hypervisor types (adds a new element to the HypervisorType enum, but allows variable display name for the hypervisor)
##### Proposed Future work:
Replace the HypervisorType from a fixed enum to an extensible registry mechanism, registered from the hypervisor plugin
#### Feature Specifications
- The new hypervisor type is internally named 'Custom' to the CloudStack services (management server and agent services, database records).
- A new global setting ‘hypervisor.custom.display.name’ allows administrators to set the display name of the hypervisor type. The display name will be shown in the CloudStack UI and API.
- In case the ‘hypervisor.list’ setting contains the display name of the new hypervisor type, the setting value is automatically updated after the ‘hypervisor.custom.display.name’ setting is updated.
- The new Custom hypervisor type supports:
- Direct downloads (the ability to download templates into primary storage from the hypervisor hosts without using secondary storage)
- Local storage (use hypervisor hosts local storage as primary storage)
- Template format: RAW format (the templates to be registered on the new hypervisor type must be in RAW format)
- The UI is also extended to display the new hypervisor type and the supported features listed above.
- The above are the minimal changes for CloudStack to support the new hypervisor type, which can be tested by integrating the plugin codebase with this feature.
#### Use cases
This PR allows the cloud administrators to test custom hypervisor plugins implementations in CloudStack and easily integrate it into CloudStack as a new hypervisor type ("Custom"), reducing the implementation to only the hypervisor supported specific storage/networking and the hypervisor resource to communicate with the management server.
- CloudStack admin should be able to create a zone for the new custom hypervisor and add clusters, hosts into the zone with normal operations
- CloudStack users should be able to execute normal VMs/volumes/network/storage operations on VMs/volumes running on the custom hypervisor hosts
* Replace Hashtable with LinkedHashMap in createIsoResponse
This change replaces the use of Hashtable with LinkedHashMap in the `createIsoResponse` method of `ViewResponseHelper`.
The reason for this modification is to maintain the insertion order of entries, which isn't the case with Hashtable.
This could lead to more predictable results and behaviors in calling methods.
* Replace Hashtable with LinkedHashMap in view response creation methods
Changed Hashtable to LinkedHashMap in various response creation methods within ViewResponseHelper class.
This modification ensures an ordered iteration which is beneficial for scenarios where the insertion order of responses needs to be maintained consistently.

When deploying a VM is failed during the allocation process it may leave the resources that have been already allocated before the failure. They will get removed from the database as the whole code block is wrapped inside a transaction twice but the server would not inform the network or storage plugins to clean up the allocated resources.
This PR removes Transactions during VM allocation which results in the allocated VM and its resource records being persisted in DB even during failures. When failure is encountered VM is moved to Error state. This helps VM and its resources to be properly deallocated when it is expunged either by a server task such as ExpungeTask or during manual expunge.

Supported Virtual machine operations:
- live migration of VM to another host
- virtual machine snapshots (group snapshot without memory)
- revert VM snapshot
- delete VM snapshot
Supported Volume operations:
- attach/detach volume
- live migrate volume between two StorPool primary storages
- volume snapshot
- delete snapshot
- revert snapshot
This PR adds a check on host's status. Without this if the agent is not in Up or Connecting state, expunging of a VM fails.
Steps to reproduce:
- Enable vm.configdrive.force.host.cache.use in Global Configuration.
- Create a L2 network with config drive
- Deploy a vm with the L2 network created in previous step
- Stop the vm and destroy vm (not expunge it)
- Stop the cloudstack-agent on the VM's host
- Expunge the vm

In troubleshooting ops issues we see logs like:
Maximum domain resource limits of Type 'user_vm' for Domain Id = 763 is exceeded: Domain Resource Limit = (1 bytes) 1, Current Domain Resource Amount = (0 bytes) 0, Requested Resource Amount = (1 bytes) 1."
However there is one missing value (currentResourceReservation) that is used in the calculation of limit check but it is not logged, which leads to confusion. Above we see we are using “0” and requested 1, with our limit being 1, but was rejected. Without logging all the values used in the calculation we don’t understand why it failed.
Additionally, if we had this log above it would be clearer that a second bug is occurring. When we query for domain level resource reservations in “getDomainReservation” the actual SearchBuilder is the listAccountAndTypeSearch, not the listDomainAndTypeSearch. As a result, when we call getDomainReservation the query returns any outstanding domain reservation for any account, as domain ID is not a valid filter for the account search.
This PR:
Increases detailed information in log for checking resource limit to include reservations information for functions: checkDomainResourceLimit() and checkAccountResourceLimit
Fixes getDomainReservation() to use listDomainAndTypeSearch instead of listAccountAndTypeSearch

This PR fixes a null pointer edge case where a PowerFlex volume is attached to a VM.
In this edge case, a VM has been created, started, stopped, and then reimaged. VM has a last host ID but the newly attached volume does not yet have a storage pool assigned, it will be assigned on the VM start. However, we assume that if the VM's host is not null, we need to try to revoke access to the volume for the host. Since there is no storage pool yet for the volume, we hit a null pointer when checking to see if the volume's pool is PowerFlex.
This was affecting all storage types, I could reproduce it with local storage, since the null pointer is at the check for pool's type.

This fix ensures when datastore cluster in VMware is added as a primary storage pool in CloudStack then all the child datastores (which already exists in CS) should be in Up state.
For example:
1. Datastore Cluster DS has two child datastores A and B in vCenter. (B is already added as a storage pool in CloudStack)
2. Now try to add datastore cluster DS into CloudStack as a primary storage pool
3. CloudStack tries to add child datastores A and B in CloudStack, since B is already there in CloudStack, it will reuse the existing storagepool entry and will keep under parent Storage pool DS.
During Step 3 we are now checking if B is Up state or not.

This PR blocks change of service offering if the offering root volume encryption values don't match. We don't support dynamically removing or adding encryption to a VM.
Signed-off-by: Marcus Sorensen <mls@apple.com>
Co-authored-by: Marcus Sorensen <mls@apple.com>
This PR introduces a feature designed to allow CloudStack to manage a generic volume encryption setting. The encryption is handled transparently to the guest OS, and is intended to handle VM guest data encryption at rest and possibly over the wire, though the actual encryption implementation is up to the primary storage driver.
In some cases cloud customers may still prefer to maintain their own guest-level volume encryption, if they don't trust the cloud provider. However, for private cloud cases this greatly simplifies the guest OS experience in terms of running volume encryption for guests without the user having to manage keys, deal with key servers and guest booting being dependent on network connectivity to them (i.e. Tang), etc, especially in cases where users are attaching/detaching data disks and moving them between VMs occasionally.
The feature can be thought of as having two parts - the API/control plane (which includes scheduling aspects), and the storage driver implementation.
This initial PR adds the encryption setting to disk offerings and service offerings (for root volume), and implements encryption support for KVM SharedMountPoint, NFS, Local, and ScaleIO storage pools.
NOTE: While not required, operations can be significantly sped up by ensuring that hosts have the `rng-tools` package and service installed and running on the management server and hypervisors. For EL hosts the service is `rngd` and for Debian it is `rng-tools`. In particular, the use of SecureRandom for generating volume passphrases can be slow if there isn't a good source of entropy. This could affect testing and build environments, and otherwise would only affect users who actually use the encryption feature. If you find tests or volume creates blocking on encryption, check this first.
### Management Server
##### API
* createDiskOffering now has an 'encrypt' Boolean
* createServiceOffering now has an 'encryptroot' Boolean. The 'root' suffix is added here in case there is ever any other need to encrypt something related to the guest configuration, like the RAM of a VM. This has been refactored to deal with the new separation of service offering from disk offering internally.
* listDiskOfferings shows encryption support on each offering, and has an encrypt boolean to choose to list only offerings that do or do not support encryption
* listServiceOfferings shows encryption support on each offering, and has an encrypt boolean to choose to list only offerings that do or do not support encryption
* listHosts now shows encryption support of each hypervisor host via `encryptionsupported`
* Volumes themselves don't show encryption on/off, rather the offering should be referenced. This follows the same pattern as other disk offering based settings such as the IOPS of the volume.
##### Volume functions
A decent effort has been made to ensure that the most common volume functions have either been cleanly supported or blocked. However, for the first release it is advised to mark this feature as *experimental*, as the code base is complex and there are certainly edge cases to be found.
Many of these features could eventually be supported over time, such as creating templates from encrypted volumes, but the effort and size of the change is already overwhelming.
Supported functions:
* Data Volume create
* VM root volume create
* VM root volume reinstall
* Offline volume snapshot/restore
* Migration of VM with storage (e.g. local storage VM migration)
* Resize volume
* Detach/attach volume
Blocked functions:
* Online volume snapshot
* VM snapshot w/memory
* Scheduled snapshots (would fail when VM is running)
* Disk offering migration to offerings that don't have matching encryption
* Creating template from encrypted volume
* Creating volume from encrypted volume
* Volume extraction (would we decrypt it first, or expose the key? Probably the former).
##### Primary Storage Support
For storage developers, adding encryption support involves:
1. Updating the `StoragePoolType` for your primary storage to advertise encryption support. This is used during allocation of storage to match storage types that support encryption to storage that supports it.
2. Implementing encryption feature when your `PrimaryDataStoreDriver` is called to perform volume lifecycle functions on volumes that are requesting encryption. You are free to do what your storage supports - this could be as simple as calling a storage API with the right flag when creating a volume. Or (as is the case with the KVM storage types), as complex as managing volume details directly at the hypervisor host. The data objects passed to the storage driver will contain volume passphrases, if encryption is requested.
##### Scheduling
For the KVM implementations specified above, we are dependent on the KVM hosts having support for volume encryption tools. As such, the hosts `StartupRoutingCommand` has been modified to advertise whether the host supports encryption. This is done via a probe during agent startup to look for functioning `cryptsetup` and support in `qemu-img`. This is also visible via the listHosts API and the host details in the UI. This was patterned after other features that require hypervisor support such as UEFI.
The `EndPointSelector` interface and `DefaultEndpointSelector` have had new methods added, which allow the caller to ask for endpoints that support encryption. This can be used by storage drivers to find the proper hosts to send storage commands that involve encryption. Not all volume activities will require a host to support encryption (for example a snapshot backup is a simple file copy), and this is the reason why the interface has been modified to allow for the storage driver to decide, rather than just passing the data objects to the EndpointSelector and letting the implementation decide.
VM scheduling has also been modified. When a VM start is requested, if any volume that requires encryption is attached, it will filter out hosts that don't support encryption.
##### DB Changes
A volume whose disk offering enables encryption will get a passphrase generated for it before its first use. This is stored in the new 'passphrase' table, and is encrypted using the CloudStack installation's standard configured DB encryption. A field has been added to the volumes table, referencing this passphrase, and a foreign key added to ensure passphrases that are referenced can't be removed from the database. The volumes table now also contains an encryption format field, which is set by the implementer of the encryption and used as it sees fit.
#### KVM Agent
For the KVM storage pool types supported, the encryption has been implemented at Qemu itself, using the built-in LUKS storage support. This means that the storage remains encrypted all the way to the VM process, and decrypted before the block device is visible to the guest. This may not be necessary in order to implement encryption for /your/ storage pool type, maybe you have a kernel driver that decrypts before the block device on the system, or something like that. However, it seemed like the simplest, common place to terminate the encryption, and provides the lowest surface area for decrypted guest data.
For qcow2 based storage, `qemu-img` is used to set up a qcow2 file with LUKS encryption. For block based (currently just ScaleIO storage), the `cryptsetup` utility is used to format the block device as LUKS for data disks, but `qemu-img` and its LUKS support is used for template copy.
Any volume that requires encryption will contain a passphrase ID as a byte array when handed down to the KVM agent. Care has been taken to ensure this doesn't get logged, and it is cleared after use in attempt to avoid exposing it before garbage collection occurs. On the agent side, this passphrase is used in two ways:
1. In cases where the volume experiences some libvirt interaction it is loaded into libvirt as an ephemeral, private secret and then referenced by secret UUID in any libvirt XML. This applies to things like VM startup, migration preparation, etc.
2. In cases where `qemu-img` needs to use this passphrase for volume operations, it is written to a `KeyFile` on the cloudstack agent's configured tmpfs and passed along. The `KeyFile` is a `Closeable` and when it is closed, it is deleted. This allows us to try-with-resources any volume operations and get the KeyFile removed regardless.
In order to support the advanced syntax required to handle encryption and passphrases with `qemu-img`, the `QemuImg` utility has been modified to support the new `--object` and `--image-opts` flags. These are modeled as `QemuObject` and `QemuImageOptions`. These `qemu-img` flags have been designed to supersede some of the existing, older flags being used today (such as choosing file formats and paths), and an effort could be made to switch over to these wholesale. However, for now we have instead opted to keep existing functions and do some wrapping to ensure backward compatibility, so callers of `QemuImg` can choose to use either way.
It should be noted that there are also a few different Enums that represent the encryption format for various purposes. While these are analogous in principle, they represent different things and should not be confused. For example, the supported encryption format strings for the `cryptsetup` utility has `LuksType.LUKS` while `QemuImg` has a `QemuImg.PhysicalDiskFormat.LUKS`.
Some additional effort could potentially be made to support advanced encryption configurations, such as choosing between LUKS1 and LUKS2 or changing cipher details. These may require changes all the way up through the control plane. However, in practice Libvirt and Qemu currently only support LUKS1 today. Additionally, the cipher details aren't required in order to use an encrypted volume, as they're stored in the LUKS header on the volume there is no need to store these elsewhere. As such, we need only set the one encryption format upon volume creation, which is persisted in the volumes table and then available later as needed. In the future when LUKS2 is standard and fully supported, we could move to it as the default and old volumes will still reference LUKS1 and have the headers on-disk to ensure they remain usable. We could also possibly support an automatic upgrade of the headers down the road, or a volume migration mechanism.
Every version of cryptsetup and qemu-img tested on variants of EL7 and Ubuntu that support encryption use the XTS-AES 256 cipher, which is the leading industry standard and widely used cipher today (e.g. BitLocker and FileVault).

This PR allows the cloud admin to set either a global or domain-specific value "metadata.allow.expose.domain", and when set this allows the VM to see the name and ID of the immediate domain that contains the VM in instance metadata. This can be useful or a variety of things such as bootstrapping VM configuration and access according to domain.
This PR also deletes the CloudZonesNetworkElement because it isn't referred to anywhere, and there was initially some confusion as to whether this code needed to be updated when extending metadata. If it needs to be kept we can remove that delete from the PR.

This PR addresses parallel resource allocation as a generalization of the problem and solution described in #6644. Instead of the Global lock on the resources a reservation record is created which is added in the resource check count in the ResourceLimitService/ResourceLimitManagerImpl. As a convenience a CheckedReservation is created. This is an implementation of AutoClosable and can be used as a guard in a try-with-resource fashion. The close method of the CheckedReservation wil delete the reservation record.
