    overcloud_containers.yaml.j2 map images to services

    This change adds a services key to each entry in
    overcloud_containers.yaml.j2 which contains a list of
    tripleo-heat-templates docker resource types which consume this image.

    The intent is for the prepare command to use this plus the heat
    environments to produce an image list that only contains images for
    services actually being deployed. This targeted list will make image
    upload operations quicker, which is one issue affecting containers in
    CI.
