    Notify more relations when cluster is bootstrapped

    Currently mon_relation only calls notify_rbd_mirrors when the cluster is
    already bootstrapped which leads to broker requests not being handled
    for other relations in some cases.

    The change also moves the bootstrap attempt code into a separate
    function and adds unit tests for mon_relation to cover different
    branches for various inputs.
