Title: [REVIEW ONLY] XD-1250 RabbitMessageBus Polishing

Several issues resolved:

1. The message bus was using unnamed auto-delete queues for pub/sub.
A connection glitch would cause such queues to be deleted and
the container could not recover.
- changed to use AnonymousQueue and configure the admin to redeclare
when necessary.

2. The module-common context was never closed so the RabbitMessageBus
containers would go into recovery mode; currently this is a hard-
wired 15 second delay (3x5 seconds).
- added a getter to the module deployer so the context can be closed.

3. Changed `RabbitSingleNodeStreamDeploymentIntegrationTests` to delete
the deployment queues after all contexts are closed.
