This PR adds new functionality to copy snapshots across zones and take snapshots for multiple zones.
Copy functionality is similar to template copy. The source zone acts as the web server from where the destination zone(s) can download the snapshot files. For this purpose, a new API - `copySnapshot` has been added. The response for copySnapshot will be returning zone and download details from the first destination zone of the request. This behaviour is similar to the `copyTemplate` API.
In a similar manner, multiple zones can be selected while taking the snapshots or creating snapshot policies. For this snapshot will be taken in the base zone(in which volume is present) and then copied to the additional zones. A new parameter - `zoneids` has been added to `createSnapshot` and `createSnapshotPolicy` APIs.
As snapshots can be present on multiple zones (secondary stores), a new parameter `zoneid` has been added to delete the snapshot copy on a specific zone.
`listSnapshots` API has been updated to allow listing snapshot entries for different zones/datastores. New parameters - `showUnique`, `locationType` have been added.
Events generated during snapshot operations will now be linked to the snapshot itself rather than the volume of the snapshot.
`listSnapshotPolicies` and `createSnapshotPolicy` APIs will return zone details of the zones in which backup will be scheduled for the policy.

Doc PR: https://github.com/apache/cloudstack-documentation/pull/344
PR: https://github.com/apache/cloudstack/pull/7873
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).

Currently, our compute offerings and disk offerings are tightly coupled with respect to many aspects. For example, if a compute offering is created, a corresponding disk offering entry is also created with the same ID as the reference. Also creating compute offering takes few disk-related parameters which anyway goes to the corresponding disk offering only. I think this design was initially made to address compute offering for the root volume created from a template. Also changing the offering of a volume is tightly coupled with storage tags and has to be done in different APIs either migrateVolume or resizeVolume. Changing of disk offering should be seamless and should consider new storage tags, new size and place the volume in appropriate state as defined in disk offering.

This PR introduces new granularity levels to configure VM dynamic scalability. Previously VM is configured to be dynamically scalable based on the template and global setting. Now we bringing this option to configure at service offering and VM level also.
VM can dynamically scale only when all flags are ON at VM level, template, service offering and global setting. If any of the flags is set to false then VM cannot be scalable. This result will be persisted in DB for each VM and will be honoured for that VM till it is updated.
We are introducing 'dynamicscalingallowed' parameter with permitted values of true or false for deployVM API and createServiceOffering API.
Following are the API parameter changes:
createServiceOffering API:
dynamicscalingenabled: an optional parameter of type Boolean with default value “true”.
deployVirtualMachine API:
dynamicscalingenabled: an optional parameter of type Boolean with default value “true”.
Following are the UI changes:
Service offering creation has ON/OFF switch for dynamic scaling enabled with default value true
If the resource state of hypervisor in "Maintenance" then it
should be considered as offline even though the agent state
is "Up". Since its in maintenance mode, it cant be used to
allocate VM's and hence can't be considered towards resource
allocation
This feature enables the following:
Balanced migration of data objects from source Image store to destination Image store(s)
Complete migration of data
setting an image store to read-only
viewing download progress of templates across all data stores
Related Primate PR: apache/cloudstack-primate#326
If projects have many resource tags, it will take a long time to list projects.
Remove resource tags information from project_view will fix it the issue.
