Suggested Action: List Unconsumed Queues

[Drew Freiberger]

I'd like to suggest we have an action that allows operators to list queues in rabbitMQ that are not consumed. This would be helpful when queues back up to know whether queues are just slowly draining, or not actually owned by a consumer or the consumer process is dead.

One example might be when setting up a new cloud, determining whether the designate.info queue is being consumed before purging it.

This would also be helpful in determining if a growing queue such as ceilometer samples is backing up from load or from a dead ceilometer process.
