Containerize HAProxy for HA
This service allows configuring and deploying HAProxy 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 HAProxy. 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.
