Description Rob Young 2016-09-27 14:41:03 UTC

Description of problem:

Pacemaker managed services should be integrated with director composable roles. The current Controller PCMK and Contoller systemd roles should be retained. New roles should be added for the following HA components so they can be deployed, upgraded and scaled independently:

RabbitMQ - required
Galera - required
HAProxy - optional, but nice to have.
Separating the remaining Pacemaker managed services is optional.
