ZFS itself does not track the refquota per snapshot, so this needs to be handled by Proxmox VE. Otherwise, rolling back a volume that has been resized since the snapshot was taken, will retain the new size. This is problematic, as it means the value in the guest config does not match the size of the disk on the storage anymore. This implementation does so by leveraging a user property per snapshot.
