* Avoid concurrent deletes modifying the same backup chain in parallel - Backup deletes are serialized by using a per-VM GlobalLock
Backup delete checks if it has a live dependent backup not just a live immediate child.
Implements incremental backup support for the NAS backup provider on KVM, using QEMU dirty bitmaps and libvirt's backup-begin API. RFC: apache/cloudstack#12899.
For large VMs this reduces daily backup storage 80–95% and shortens backup windows from hours to minutes (e.g. a 500 GB VM with moderate writes goes from ~500 GB/day to ~5–15 GB/day after the initial full backup).

* Fix NPE in NASBackupProvider when no running KVM host is available
ResourceManager.findOneRandomRunningHostByHypervisor() can return null
when no KVM host in the zone has status=Up (e.g. during management
server startup, brief agent disconnections, or host state transitions).
NASBackupProvider.syncBackupStorageStats() and deleteBackup() call
host.getId() without a null check, causing a NullPointerException that
crashes the entire BackupSyncTask background job every sync interval.
This adds null checks in both methods:
- syncBackupStorageStats: log a warning and return early
- deleteBackup: throw CloudRuntimeException with a descriptive message

This PR aligns the use of terminology, renaming VM / virtual machine references to 'Instance' and also capitalising the terms Templates, Network, Snapshot, User, Account in CloudStack APIs, error and log messages, events, tooltips, etc. Many typos, grammar and spelling mistakes were fixed, also terms like IPv4, VPN, VPC, etc. were properly capitalised. Some error messages were cleaned for better readability. The test cases, expecting some exception strings were adjusted accordingly.
Here is the wiki page, describing the changes in details:

This feature adds the ability to create a new instance from a VM backup for dummy, NAS and Veeam backup providers. It works even if the original instance used to create the backup was expunged or unmanaged. There are two parts to this functionality:
Saving all configuration details that the VM had at the time of taking the backup. And using them to create an instance from backup.
Enabling a user to expunge/unmanage an instance that has backups.
