    Lock storage nodes during system restore

    Currently, as part of system restore, maintenance will lock all the
    nodes except for controller-0. When locking storage nodes if the
    replication will be lost, we query ceph pools to see if they are
    empty. But during restore, ceph cluster is not up yet; therefore
    query ceph pools will fail and it will block locking storage nodes.

    Solution: In the case of the restore, if it is a force-lock, we
    should skip the ceph pool query and just lock the storage node.
