title: Set RabbitMq .outq as durable with ServiceStack
body: <p>Our queues are automatically created when calling mqServer.CreateMessageQueueClient().Publish(). Recently we had an issue with a RabbitMq server going down and since ServiceStack does not create the outq as durable, the queue data was lost. Is there a way to change the queue to durable?  I believe this has to be done in ServiceStack since that's where the queues are created.</p>
  
  <p>Perhaps I'm approaching the issue from the wrong direction.</p>
