[pve-devel] [PATCH-SERIES] remove replicated volumes on guest purge

[Fabian Ebner <f.ebner@proxmox.com>]

Introduces two helper functions in Replication.pm and ReplicationConfig.pm
so that the guests can do the removal easily.

destroy_vm contains a check whether the guest is still in use by a
linked clone (in the LXC case triggered by the storage backend at vdisk_free),
so that needs to happen first.
That check could be factored out and removing replicated volumes moved
to before destroy_vm, but I feel like it's cleaner to first destroy the
VM and do all related cleanups later (as it is now).

The problem is that the guest config does not contain any volumes
after destroy_vm, and run_full_removal would do nothing, because
on removal, run_replication currently only considers storages that
show up in the config and not those from the replication job state.

Therefore, this depends on the following patch to be applied first:

Dependency bumps: qemu-server,pve-container -> pve-guest-common
are needed for patches #2 and #3
and I think the reverse bumps are needed for patch #4
