Story #8061: develop queue-based processing system for the CN

The rabbitmq queues should be replicated across machines, so failure of one or two machines could be restored from the remaining. This is the case with much of the CN infrastructure.
Second, the information contained in the queues could be restored by reindexing content that has been added or modified since time before the failure.
Hence it seems that it should be sufficient to ensure that the rabbitmq configuration is preserved to enable the instances to be reinstalled as necessary.
