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.

ACS + Xenserver works with differential snapshots. ACS takes a volume full snapshot and the next ones are referenced as a child of the previous snapshot until the chain reaches the limit defined in the global setting snapshot.delta.max; then, a new full snapshot is taken. PR #5297 introduced disk-only snapshots for KVM volumes. Among the changes, the delete process was also refactored. Before the changes, when one was removing a snapshot with children, ACS was marking it as Destroyed and it was keeping the Image entry on the table cloud.snapshot_store_ref as Ready. When ACS was rotating the snapshots (the max delta was reached) and all the children were already marked as removed; then, ACS would start removing the whole hierarchy, completing the differential snapshot cycle. After the changes, the snapshots with children stopped being marked as removed and the differential snapshot cycle was not being completed.
This PR intends to honor again the differential snapshot cycle for XenServer, making the snapshots to be marked as removed when deleted while having children and following the differential snapshot cycle.
Also, when one takes a volume snapshot and ACS backs it up to the secondary storage, ACS inserts 2 entries on table cloud.snapshot_store_ref (Primary and Image). When one deletes a volume snapshot, ACS first tries to remove the snapshot from the secondary storage and mark the entry Image as removed; then, it tries to remove the snapshot from the primary storage and mark the entry Primary as removed. If ACS cannot remove the snapshot from the primary storage, it will keep the snapshot as BackedUp; however, If it does not exist in the secondary storage and without the entry SNAPSHOT.DELETE on cloud.usage_event. In the end, after the garbage collector flow, the snapshot will be marked as BackedUp, with a value in the field removed and still being rated. This PR also addresses the correction for this situation.

This PR fixes the issue #6209 where the snapshot revert operation fails after certain volume operations like Migrate VM with volume / migrate volume / reinstall VM.
The root cause of the issue after these volume operations, the primary storage entry is getting deleted for that volume. We have fixed it here to get the primary datastore entry wrt volume and continue the operation.
* Refactor create volume snapshot with running VM
* Refactor create volume snapshot with stopped VM
* Refactor create volume from snapshot
* Refactor create template from snapshot
* Refactor volume migration (migrateVolume/ migrateVirtualMachineWithVolume)
* Refactor snapshot deletion
* Refactor snapshot revertion
* Adjusts and fix cherry-pick conflicts
* Remove diffuse tests
* Add validation to add flag '--delete' on command 'virsh blockcommand' only if libvirt version is equal or higher 6.0.0
* Expunge temporary snapshot only if template creation is from snapshot
* Extract strings to constant
* Remove unused imports
* Fix error on revert backed up snapshot
* Turn method's return to void as it is not used
* Rename method in SnapshotHelper

* VM snapshots of running KVM instance using storage providers plugins for disk snapshots
Added new virtual machine snapshot strategy which is using storage providers plugins to take/revert/delete snapshots.
You can take VM snapshot without VM memory on KVM instance, using storage providers implementations for disk snapshots.
Also revert and delete is added as functionality. Added Thaw/Freeze command for KVM instance.
The snapshots will be consistent, because we freeze the VM during the snapshotting. Backup to secondary storage is executed after
thaw of the VM and if it is enabled in global settings.
* Removed duplicated functionality
Set few methods in DefaultVMSnapshotStrategy to protected to reuse them
without duplicating the code. Remove code that is actualy not needed
* Added requirements in global setting kvm.vmstoragesnapshot.enabled
Added more information in kvm.vmstoragesnapshot.enabled global setting,
that it needs installation of:
- qemu version 1.6+
- qemu-guest-agent installed on guest virtual machine
when the option is enabled
* Added Apache license header
* Removed commented code
* If "kvm.vmstoragesnapshot.enabled" is null should be considered as false
* removed unused imports, replaced default template
Removed unused imports which causing failures and replaced template to
CentOS8
* "kvm.vmstoragesnapshot.enabled" set to dynamic
* Getting status of freeze/thaw commands not the return code
Will chacke the status if freeze/thaw of Guest VM succeded, rather than
looking for return code. Code refactoring
* removed "CreatingKVM" VMsnapshot state and events related to it
* renamed AllocatedKVM to AllocatedVM
the states should not be associated to a hypervisor type
* loggin the result of "drive-backup" command
* Check which VM snapshot strategy could handle the vm snapshots
gets the best match of VM snapshot strategy which could handle the vm
snapshots on KVM.
Other storage plugins could integrate with this functionality to support group snapshots
* Added poolId in canHandle for KVM hypervisors
Added poolId into canHandle method used to check if all volumes are on
the same PowerFlex's storage pool
* skip smoke tests if the hypervisor's OS type is CentOS
This PR works with functionality included in qemu-kvm-ev which
does not come by default on CentOS. The smoke tests will be skipped if
the hypervisor OS is CentOS
* Added missed import in smoke test
* Suggested change to use ` org.apache.commons.lang.StringUtils.isNotBlank`
* Fix getting device on Ubuntu
On Ubuntu the device isn't provided and we have to get it from
node-name parameter. For drive-backup command (for Ubuntu) is needed and job-id which
is the value of node-name (this extra param works on Ubuntu and CentOS as well).
* Removed new snapshot states and functionality for NFS
* throw CloudRuntimeException
provide a properer error message when delete VM snapshot fails
* exclude GROUP snapshots when listing snapshots
* Skip tests if there is pool with NFS/Local
* address comments

Add CephSnapshotStrategy to handle RBD revert (rollback) snapshot. In order to support RBD revert (rbd_rollback), this PR adds a CephSnapshotStrategy class to handle Ceph/RBD snapshot actions.
* rename package from "src" to "org.apache.cloudstack.storage.vmsnapshot"
* Remove Empty test class "SnapshotDataFactoryTest"
* Remove redundant imports (importing a class from its own package)
* Fix the problem at #1740 when it loads all snapshots in the primary storage
While checking a problem with @mike-tutkowski at PR #1740, we noticed that the method `org.apache.cloudstack.storage.snapshot.SnapshotDataFactoryImpl.getSnapshots(long, DataStoreRole)` was not loading the snapshots in `snapshot_store_ref` table according to their storage role. Instead, it would return a list of all snapshots (even if they are not in the storage role sent as a parameter) saying that they are in the storage that was sent as parameter.
* Add unit test
Remove maven standard module (which only a few were using) and get ride of maven customization for the projects structure.
- moved all directories to src/main/java, src/main/resources, src/main/scripts, src/test/java, src/test/resources
- grep scan to search for src/com and src/org left over
- grep for <project>/scripts to fix pom.xml configuration
- remove custom <build> configuration in pom.xml
