Draining queues should be responsibility of the broker and based on policy configured in brokers
config file.

> ActiveMQ currently doesnt evict expried messages from the Dead Letter Queue. This can
potentially lead to Out Of Memory situation as by default the broker keeps all messages in
memory. One possible strategy is to modify ActiveMQ broker configuration to spool messages
from the DLQ to disk when memory is tight. Other strategy may involve creating a custom DLQ
Consumer to drain messages.
