So in MQTT the concept of QoS combines the AMQP concepts of ack mode and 
delivery mode; publishing with QoS 1 is the equivalent of publishing 
persistent messages in confirm mode.

However, I am not sure that the RabbitMQ MQTT plugin actually does this; 
it looks like it publishes transient messages only. I will file a bug to 
fix that.
