[pve-devel] [PATCH storage] pbs: use vmid parameter in list_snapshots

Particularly for operations such as pruning backups after a
scheduled backups we do not want to list the entire
store.

(pbs_api_connect is moved up unmodified)

Note that the 'snapshots' CLI command only takes a full
group, but the API does allow specifying a backup-id without
a backup-type!
