title: RabbitMQ - high availability queues - but w/o messages replication
body: <p>I want to configure a RabbitMQ cluster between two nodes and I'm aiming for the active/passive approach in a way that if the master RabbitMQ is down for a reason I will route all traffic to the passive RabbitMQ ( via Haproxy or something ).</p>
  
  <p>Basically I don't want to <strong>replicate the messages to the passive brocker</strong>, I need only the metadata ( queues/exchanges/bindings ), 
  Does someone know if there is a way to sync only the metadata between the two rabbits ( w/o the messages ) ?</p>
  
  <p>Thanks</p>
