Fix transport_url

We have observed that omitting statefulset
on the olso_messaging values can cause octavia
workers to ocasionally fail with:

AMQP server on rabbitmq.openstack.svc.cluster.local:5672 is unreachable:
[Errno 104] Connection reset by peer. Trying again in 1 seconds.:
ConnectionResetError: [Errno 104] Connection reset by peer

This patch aims to keep the pattern used on the other serivces
to setup the transport_url that includes all pods in the statefulset.
