    Run Glance initialization when Glance is enabled, not just registry (v2)

    Per [1] Glance registry should not be required to run since Queens.

    v2 improves on v1 [2] (now reverted [3]) by applying minor comments
    from reviews so far and ensuring nova-live-migration job does not see
    a change in behavior and hence does not break [4].
    [5] tried to fix the issue but it did only partially, regarding
    the database but not the image upload [6].
    This patch ensures double cirros image upload does not happen as well.
