Subject: [PATCH] rabbitmq: Switch to using volume claim templates

This will make it easier to "blow away" the RabbitMQ data volume on the
occasions when it gets into a weird state.  Simply scale the StatefulSet
down to 0 replicas, delete the PVC, then scale back up.  Kubernetes will
handle creating a new PVC automatically.
