       The consumer tag is valid only within the channel from which the
       consumer was created. I.e. a client MUST NOT create a consumer in
       one channel and then use it in another.

     If the no-local field is set the server will not send messages to
     the client that published them.

       If this field is set the server does not expect acknowledgments
       for messages.  That is, when a message is delivered to the client
       the server automatically and silently acknowledges it on behalf
       of the client.  This functionality increases performance but at
       the cost of reliability.  Messages can get lost if a client dies
       before it can deliver them to the application.
