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

* 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

BackupSync task would switch between databases to update backup usage
metrics in the cloud_usage.usage_backup table. The current framework
and the usage in ManagedContext causes database connection
(LegacyTransaction) leaks. When the thread runs faster, the issue is
easily reproducible and checking via heap dump analysis or using JMX
MBeans. This fixes by moving the task of backup data updation for
usage data to the usage server by publishing usage events instead of
switching between databases in a local thread while in a
ManagedContextRunnable.
