[PVE-User] Bug when removing a VM

[lemonnierk at ulrar.net]

Well we have too many clusters for not repeating IDs, keeping track
would be pretty hard.

Can't really use "mv" to migrate, the downtime would be huge, that's why
we use the "move disk" option to do it online. All of that works great,
just find that really really strange that proxmox deletes the directory
everywhere, not just on the related storage. At the very least a warning
would be nice, maybe even a list of the files it's going to remove if
you press the button ? That way you can check it's valid
