    Forget cluster node as an action

    There are race conditions in which the forget_cluster_node can get
    executed against a node that is in the process of joining the cluster.

    This change moves forget_cluster_node to an action that can be
    performed by the administrator. The asses_cluster_status has been
    updated to check for departed nodes and set status pointing toward the
    use of the new forget-cluster-node action.
