title: To be sure about concurrency, same group of works in multiple queues (FIFO)
body: <p>I have a question about multi consumer concurrency.
  I want to send works to rabbitmq that comes from web request to distributed queues.
  I just want to be sure about order of works in multiple queues (FIFO).
  Because this request comes from different users eech user requests/works must be ordered.</p>
  
  <p>I have found this feature with different names on Azure ServiceBus and ActiveMQ message grouping.</p>
  
  <p>Is there any way to do this in pretty RabbitMQ ? </p>
  
  <p>I want to quaranty that customer's requests must be ordered each other. 
  Each customer may have multiple requests but those requests for that customer must be processed in order.
  I desire to process quickly incoming requests with using multiple consumer on different nodes. 
  For example different customers 1 to 1000 send requests over 1 millions. 
  If I put this huge request in only one queue it takes a lot of time to consume. So I want to share this process load between n (5) node. For customer X 's requests must be in same sequence for processing</p>
