docs: confirms a queue definition
  
          This method confirms a Declare method and confirms the name of
          the queue, essential for automatically-named queues.
  
          PARAMETERS:
              queue: shortstr
  
                  Reports the name of the queue. If the server generated
                  a queue name, this field contains that name.
  
              message_count: long
  
                  number of messages in queue
  
                  Reports the number of messages in the queue, which
                  will be zero for newly-created queues.
  
              consumer_count: long
  
                  number of consumers
  
                  Reports the number of active consumers for the queue.
                  Note that consumers can suspend activity
                  (Channel.Flow) in which case they do not appear in
                  this count.
