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.
