This is a simple NAS backup plugin for KVM which may be later expanded for other hypervisors. This backup plugin aims to use shared NAS storage on KVM hosts such as NFS (or CephFS and others in future), which is used to backup fully cloned VMs for backup & restore operations. This may NOT be as efficient and performant as some of the other B&R providers, but maybe useful for some KVM environments who are okay to only have full-instance backups and limited functionality.
Design & Implementation follows the `networker` B&R plugin, which is simply:
- Implement B&R plugin interfaces
- Use cmd-answer pattern to execute backup and restore operations on KVM host when VM is running (or needs to be restored) - instead of a B&R API client, relies on answers from KVM agent which executes the operations
- Backups are full VM domain snapshots, copied to a VM-specific folders on a NAS target (NFS) along with a domain XML
- Backup uses libvirt feature: https://libvirt.org/kbase/live_full_disk_backup.html orchestrated via virsh/bash script (nasbackup.sh) as the libvirt-java lacks the bindings
- Supported instance volume storage for restore operations: NFS & local storage

This feature adds support for Ceph's RADOS Gateway (RGW) support for the
Object Store feature of CloudStack.
The RGW of Ceph is Amazon S3 compliant and is therefor an easy and straigforward
implementation of basic S3 features.
Existing Ceph environments can have the RGW added as an additional feature to a
cluster already providing RBD (Block Device) to a CloudStack environment.
Introduce the BucketTO to pass to the drivers. This replaces just passing the bucket's name.
Some upcoming drivers require more information then just the bucket name to perform their actions,
for example they require the access and secret key which belong to the account of this bucket.
This is leftover code from a long time ago and this validation test has nu influence
on the end result on how a URL will be used afterwards.
We should support hosts pointing to an IPv6(-only) address out of the box.
For the code it does not matter if it's IPv4 or IPv6. This is the admin's choice.

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:
https://dev.mysql.com/doc/connector-j/en/connector-j-usagenotes-j2ee-concepts-connection-pooling.html
Replaces dbcp2 connection pool library with more performant HikariCP.
With this unit tests are failing but build is passing.

Added caching for ConfigKey value retrievals based on the Caffeine
in-memory caching library.
https://github.com/ben-manes/caffeine
Currently, expire time for a cache is 30s and each update of the
config key invalidates the cache. On any update or reset of the
configuration, cache automatically invalidates for it.

This PR makes sure a KVM VM gets the UUID of the VM as a static serialnumber through smbios.
Some applications on primarily Windows servers require a stable serial number for licensing purposes. By providing this serial number we can make sure these applications can have a license configured.

vm
Fixes#8645
When a local storage volume is being attached to a stopped VM, volume
migration is only needed when it is not present on the last host as the
current host ID will be null in the database.
