    Fix to ensure that glance responds to cluster-relation-departed

    When a glance unit is removed a 'cluster-relation-departed' is sent to
    each of the remaining units. This was not being used, but the
    side-effect was that the hacluster.cfg file was not being updated which
    left the now deleted unit haproxy.cfg. This change just tags on the
    hook for 'cluster-relation-departed' to the function that handles
    'cluster-relation-changed' so that the haproxy.cfg file gets updated.
