Containerize Redis for HA
This service allows configuring and deploying Redis containers in a HA overcloud managed by pacemaker. The containers are managed and run by pacemaker. Inside there is pacemaker_remote which will invoke the resource agent managing galera. The resources themselves are created via puppet-pacemaker inside a short-lived container used for this purpose (mysql_init_bundle). 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.
