docs: Confirm that you've done as you were told.  Call this from your control callback to confirm action.
          Used when you are advertising a control and you want to tell the remote requestor that you have
          done what they asked you to.
  
          `Example:` this is a minimal example to show the idea.  Note - no Exception handling and ugly use of globals
  
              #!python
              client = None
  
              def controlreq_cb(args):
                  global client   # the client object you connected with
  
                  # perform your action with the data they sent
                  success = do_control_action(args['data'])
  
                  if args['confirm']:  # you've been asked to confirm
                      client.confirm_tell(args, success)
                  # else, if you do not confirm_tell() this causes a timeout at the requestor's end.
