Title: AMQP-221 Support Dead Letter Queues

Support DLQ - the listener must throw an AmqpRejectAndDontRequeueException
and this will send a basic.reject with requeue false (instead of the
default true).

There is an issue with Rabbit DLQ handling with durable queues so,
currently, this only works when dead-lettering messages sent to
non-durable queues.
