The following might work: a separate app/thread/etc could check the number of
consumers on a queue and purge it, then all messages in the ready state
should be dead-lettered. To check a number of consumers on queue, declare it
(e.g. as passive) and check the returned value, QueueDeclareOk#ConsumerCount.
