When removing an incremental snapshot (For both KVM and XenServer), it is checked if the snapshot has a child or not. If it has, then the snapshot is not removed from the storage.
For KVM incremental snapshots, snapshots in the same chain may be on different secondary storages (within the same zone).
However, the child search process only considers snapshots from the same secondary storage as theirs. Therefore, if a snapshot has its parent snapshot on a different secondary storage, it will be completely removed, making the snapshot chain inconsistent.

Per docs, if the mysql connector is JDBC2 compliant then it should use
the Connection.isValid API to test a connection.
(https://docs.oracle.com/javase/8/docs/api/java/sql/Connection.html#isValid-int-)
This would significantly reduce query lags and API throughput, as for
every SQL query one or two SELECT 1 are performed everytime a Connection
is given to application logic.
This should only be accepted when the driver is JDBC4 complaint.
As per the docs, the connector-j can use /* ping */ before calling
SELECT 1 to have light weight application pings to the server:

Replaces dbcp2 connection pool library with more performant HikariCP.
With this unit tests are failing but build is passing.

Using XenServer as the hypervisor, when deleting a snapshot that has a parent, that parent will also get erased on storage, causing data loss. This behavior was introduced with #7873, where the list of snapshot states that can be deleted was changed to add BackedUp snapshots.
This PR changes the states list back to the original list, and swaps the while loop for a do while loop to account for the changes in #7873.
Fixes#9446
* Normalize logs
All classes that could have their loggers inherited from their fathers had their own loggers deleted;
Most loggers didn't have to be static, so most of them were normalized so that they wouldn't be;
All loggers are protected now;
Static logger's name are now 'LOGGER';
Non-static logger's name are now 'logger';
New class DbUpgradeAbstractImpl created so that all Upgraders extend it and inherit its logger

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.

This removes the conditional logic where comment notest to remove it
after PR #5297 is merged that is applicable for ACS 4.18+. Only when the
global setting is enabled and memory isn't selected, VM snapshot could
be allowed for VMs on KVM that have qemu-guest-agent running.

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.
