title: RabbitMQ and authorization
body: <p>One of my projects requires authentication for using RabbitMQ. Only authenticated users can connect to the rabbitmq server and subscribe to queues etc. For example, when a user connects to the server for the first time and sends some auth data (like login, password) - server should check it and, if the user passed authentication, he will be able to subscribe to queues etc. Otherwise, the server would disconnect the user. Is there a solution for this?</p>
  
  <p>Please don't judge too harshly, I'm not really familiar with RabbitMQ and stuff like this.</p>
