    Add image_source to containers

    Previously when containers were added to the upstream kolla project or
    added to our container list, the container build process might try and
    build them when we execute kolla-build. This change adds a image_source
    parameter that is used to understand when we should and should not
    attempt to build the container with kolla witht he 'overcloud container
    image build' command.
