    [ROCKY-Only] Trigger container update on image id update

    NOTE: Rocky is missing a few backports so this patch is rocky specific.

    If you reuse a container tag for a new image, paunch does not currently
    rebuild the container to get the new image. This change adds logic to
    the updated check to also check the image id defined in the container
    instance against the image id for the image to see if the container
    image has changed.
