title: RabbitMQ - cannot delete queue
body: <p>We had a network network partition and RabbitMQ ended up in "split brain". </p>
  
  <p>After the cluster recovered, I have a queue that I cant delete. In the mgmt. interface the queue is just listed with "?", and I'm unable to delete it from using mgmt. interface or from commandline.</p>
  
  <p>I have tried to remove the node "sh-mq-cl1a-04" from the cluster, but the queue remains in the cluster.</p>
