    Containerize Cinder-backup for HA

    This service allows configuring and deploying cinder-backup
    containers in a HA overcloud managed by pacemaker.

    The containers are managed and run by pacemaker. Pacemaker runs the
    standard Kolla image but overrides the initial command so that
    it explicitely calls cinder-backup. This way, we shield ourselves
    from any unexpected future change in Kolla.
    This container needs to use the 'docker_config' section to invoke
    puppet (as opposed to 'docker_puppet_tasks'), because due to the HA
    composability each resource creation needs to happen on the bootstrap
    node of that service and 'docker_puppet_tasks' will only run on the
    controller/primary role.
