title: Conversion from MQTT to AMQP/STOMP
body: <p>I'm kind of new to these protocols, and just started exploring Message brokers like Apache Apollo and RabbitMQ. 
  So my broker receives MQTT messages from a publisher. And I would like to convert it into AMQP (preferably) or STOMP protocol to send to a web server. But I've so far been unable to do so. 
  I looked into RabbitMQ, and tried enabling the MQTT plugin, but when I do load it, I'm unable to start the server. 
  I was wondering if anyone can guide me here? Is there an API that can help me? And I'm very confused about RabbitMQ. I've been able to load other plugins easily,like stomp, management utilities etc.</p>
