    Add 'deployed_before' flag to cluster that forbids stop deployment

    When cluster is successfuly deployed, that is, has 'operational' status,
    'deployed_before' key is added to generated attributes of the cluster.
    This flag then is used to determine whether stop action is allowed for
    the cluster.
