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.

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:

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
* support for handling incremental snaps (on DB entries) on xen
* Addressed comments
* Update NfsSecondaryStorageResource.java

This PR adds minor version support when mounting nfs on the SSVM as requested in #2861
The global setting "secstorage.nfs.version" has been changed to use the String data type which allows any minor version to be specified.
As previously described by PR #3929:
If vm has attached ISO, the migration fails with error message "org.libvirt.LibvirtException: Cannot access storage file /mnt/b33e5a1d-e4ea-3465-b6ac-c98dc8ff8af0/207-2-cc5fd717-2d57-3bb3-bcf6-2c930268db6c.iso"
Fixes#3191
When a template is registered, code stores md5sum of the downloaded file in the vm_template table. However, this downloaded file could be deleted after template installation if it is not an actual (.qcow2, .ova, etc.) file. When the user copies a template using copyTemplate API, the actual template file will be copied across the image stores. Matching checksum for the copied templated file and the stored value from the vm_template table will result in a mismatch.
Changes will set an empty checksum value for the copied template while passing to download service which allows skipping wrong checksum check for the copied while install.
However, this results in a change in checksum value for concerned template entry in vm_template table post template install.
