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

Datastore cluster as a primary storage support is already there. But if any changes at vCenter to datastore cluster like addition/removal of datastore is not synchronised with CloudStack directly. It needs removal of primary storage from CloudStack and add it again to CloudStack.
Here synchronisation of datastore cluster is fixed without need to remove or add the datastore cluster.
1. A new API is introduced syncStoragePool which takes datastore cluster storage pool UUID as the parameter. This API checks if there any changes in the datastore cluster and updates management server accordingly.
2. During synchronisation if a new child datastore is found in datastore cluster, then management server will create a new child storage pool in database under the datastore cluster. If the new child storage pool is already added as an individual storage pool then the existing storage pool entry will be converted to child storage pool (instead of creating a new storage pool entry)
3. During synchronisaton if the existing child datastore in CloudStack is found to be removed on vCenter then management server removes that child datastore from datastore cluster and makes it an individual storage pool.
The above behaviour is on par with the vCenter behaviour when adding and removing child datastore.
This NPE may happen when a VM is marked removed in the DB but not its
nics on a shared network. This can usually happen due to a failed
expunged VM or when an admin manually marks a VM as removed in DB but
does not cleanup the nics/network resources.

This PR addresses the issue raised at #4545 (Fail to change Service offering from local <> shared storage).
When upgrading a VM service offering it is validated if the new offering has the same storage scope (local or shared) as the current offering. I think that the validation makes sense in a way of preventing running Root disks with an offering that does not match the current storage pool. However, the validation only compares both offerings and does not consider that it is possible to migrate Volumes between local <> shared storage pools.
The idea behind this implementation is that CloudStack should check the scope of the current storage pool which the ROOT volume is allocated; this, it is possible to migrate the volume between storage pools and list/upgrade according to the offerings that are supported for such pool.
This PR also fixes an issue where the API command that lists offerings for a VM should follow the same idea and list based on the storage pool that the volume is allocated and not the previous offering.

This PR fixes: #4462
Problem Statement:
In case of VMware, when a VM having multiple data disk is destroyed (without expunge) and tried to recover the VM then the previous data disks are not attached to the VM like before destroy. Only root disk is attached to the VM.
Root cause:
All data disks were removed as part of VM destroy. Only the volumes which are selected to delete (while destroying VM) are supposed to be detached and destroyed.
Solution:
During VM destroy, detach and destroy only volumes which are selected during VM destroy. Detach the other volumes during expunge of VM.
If VM details contain rootdisksize, volume entry in DB should reflect correct size when VM reset is performed.

This PR fixes the issue pertaining to volume resize on VMWare for deploy as-is templates. VMware deploy as-is templates are those that are deployed as per the specification in the imported OVF. Hence override root disk size will not be adhered to for such templates. Moreover, when we deploy VMs in stopped state and resize the volume, the root disk doesn't get resized but the volume size is merely updated in the DB.
This PR also includes the following (for deploy as-is templates):
- Disables overriding root disk size during VM deployment on the UI
- Disables selection of compute offerings with root disk size specified, at the time of deployment
- Provided users with the option to deploy VM is stopped state via UI (so as to give an option to users to resize the volumes before starting the VM)

This PR aims at restoring the previous level of leniency in listing templates on stores that have been marked as deleted / removed by updating the DB.
While Cloudstack doesn't allow deleting stores that have resources on them, it may so happen that users may mimic a deletion of a store by merely updating the DB. Under such a case, listing of templates is hampered due to an NPE that is caused. (as seen in #4606)

Added support for PowerFlex/ScaleIO (v3.5 onwards) storage pool as a primary storage in CloudStack (for KVM hypervisor) and enabled VM/Volume operations on that pool (using pool tag).
Please find more details in the FS here:
https://cwiki.apache.org/confluence/x/cDl4CQ
Documentation PR: apache/cloudstack-documentation#169
This enables support for PowerFlex/ScaleIO (v3.5 onwards) storage pool as a primary storage in CloudStack
Other improvements addressed in addition to PowerFlex/ScaleIO support:
- Added support for config drives in host cache for KVM
=> Changed configuration "vm.configdrive.primarypool.enabled" scope from Global to Zone level
=> Introduced new zone level configuration "vm.configdrive.force.host.cache.use" (default: false) to force host cache for config drives
=> Introduced new zone level configuration "vm.configdrive.use.host.cache.on.unsupported.pool" (default: true) to use host cache for config drives when storage pool doesn't support config drive
=> Added new parameter "host.cache.location" (default: /var/cache/cloud) in KVM agent.properties for specifying the host cache path and create config drives on the "/config" directory on the host cache path
=> Maintain the config drive location and use it when required on any config drive operation (migrate, delete)
- Detect virtual size from the template URL while registering direct download qcow2 (of KVM hypervisor) templates
- Updated full deployment destination for preparing the network(s) on VM start
- Propagate the direct download certificates uploaded to the newly added KVM hosts
- Discover the template size for direct download templates using any available host from the zones specified on template registration
=> When zones are not specified while registering template, template size discovery is performed using any available host, which is picked up randomly from one of the available zones
- Release the VM resources when VM is sync-ed to Stopped state on PowerReportMissing (after graceful period)
- Retry VM deployment/start when the host cannot grant access to volume/template
- Mark never-used or downloaded templates as Destroyed on deletion, without sending any DeleteCommand
=> Do not trigger any DeleteCommand for never-used or downloaded templates as these doesn't exist and cannot be deleted from the datastore
- Check the router filesystem is writable or not, before performing health checks
=> Introduce a new test "filesystem.writable.test" to check the filesystem is writable or not
=> The router health checks keeps the config info at "/var/cache/cloud" and updates the monitor results at "/root" for health checks, both are different partitions. So, test at both the locations.
=> Added new script: "filesystem_writable_check.py" at /opt/cloud/bin/ to check the filesystem is writable or not
- Fixed NPE issue, template is null for DATA disks. Copy template to target storage for ROOT disk (with template id), skip DATA disk(s)
* Addressed some issues for few operations on PowerFlex storage pool.
- Updated migration volume operation to sync the status and wait for migration to complete.
- Updated VM Snapshot naming, for uniqueness in ScaleIO volume name when more than one volume exists in the VM.
- Added sync lock while spooling managed storage template before volume creation from the template (non-direct download).
- Updated resize volume error message string.
- Blocked the below operations on PowerFlex storage pool:
-> Extract Volume
-> Create Snapshot for VMSnapshot
* Added the PowerFlex/ScaleIO client connection pool to manage the ScaleIO gateway clients, which uses a single gateway client per Powerflex/ScaleIO storage pool and renews it when the session token expires.
- The token is valid for 8 hours from the time it was created, unless there has been no activity for 10 minutes.

Other fixes included:
- Fail the VM deployment when the host specified in the deployVirtualMachine cmd is not in the right state (i.e. either Resource State is not Enabled or Status is not Up)
- Use the physical file size of the template to check the free space availability on the host, while downloading the direct download templates.
- Perform basic tests (for connectivity and file system) on router before updating the health check config data
=> Validate the basic tests (connectivity and file system check) on router
=> Cleanup the health check results when router is destroyed
* Updated PowerFlex/ScaleIO storage plugin version to 4.16.0.0
* UI Changes to support storage plugin for PowerFlex/ScaleIO storage pool.
- PowerFlex pool URL generated from the UI inputs(Gateway, Username, Password, Storage Pool) when adding "PowerFlex" Primary Storage
- Updated protocol to "custom" for PowerFlex provider
- Allow VM Snapshot for stopped VM on KVM hypervisor and PowerFlex/ScaleIO storage pool
and Minor improvements in PowerFlex/ScaleIO storage plugin code
* Added support for PowerFlex/ScaleIO volume migration across different PowerFlex storage instances.
- findStoragePoolsForMigration API returns PowerFlex pool(s) of different instance as suitable pool(s), for volume(s) on PowerFlex storage pool.
- Volume(s) with snapshots are not allowed to migrate to different PowerFlex instance.
- Volume(s) of running VM are not allowed to migrate to other PowerFlex storage pools.
- Volume migration from PowerFlex pool to Non-PowerFlex pool, and vice versa are not supported.
* Fixed change service offering smoke tests in test_service_offerings.py, test_vm_snapshots.py
* Added the PowerFlex/ScaleIO volume/snapshot name to the paths of respective CloudStack resources (Templates, Volumes, Snapshots and VM Snapshots)
* Added new response parameter “supportsStorageSnapshot” (true/false) to volume response, and Updated UI to hide the async backup option while taking snapshot for volume(s) with storage snapshot support.
* Fix to remove the duplicate zone wide pools listed while finding storage pools for migration
* Updated PowerFlex/ScaleIO volume migration checks and rollback migration on failure
* Fixed the PowerFlex/ScaleIO volume name inconsistency issue in the volume path after migration, due to rename failure
