> add support for specifying a maximum for message delivery attempts before moving messages to a dead letter queue.
> At a basic level, the features will work as follows: the consumer track the number of times it has seen a message without successfull delivery, and when this count is met/exceeded then during session rollback or recover it will cause the message to be rejected with request not to be requeued. The broker will be able to be configured when creating a queue as to whether or not it need support such dead-lettering and set up the requisite alternate exchange to route the messages to when they are rejected in this way. If enabled, then a fanout exchange will be created as the alternate exchange for the queue with a single queue bound, such that there is a 1:1 mapping of original queue and DLQ.
