John Garbutt fd30dfb867 Set RabbitMQ message TTL and queue expiry
Following ideas here:
https://wiki.openstack.org/wiki/Large_Scale_Configuration_Rabbit

Make sure old messages with no consumer are dropped after the message
TTL of 10 mins, longer than the 1 min RPC timeout.
Also ensure queues expire after an hour of inactivity, so queues from
removed nodes or renamed nodes don't grow over time.

In RabbitMQ, messages now have a TTL of 10 minutes and inactive queues will
expire after 1 hour. These queue arguments can be changed dynamically at
runtime [1], but it should be noted that applying a TTL to queues which
already have messages will discard the messages when specific events occur.
See [2] for more details. Note that the contents of the RabbitMQ
definitions.json are now changed, meaning RabbitMQ containers will be
restarted on next deploy/upgrade.
