docs: Send an inform message to a particular client.
  
          Should only be used for asynchronous informs. Informs
          that are part of the response to a request should use
          :meth:`reply_inform` so that the message identifier
          from the original request can be attached to the
          inform.
  
          Parameters
          ----------
          msg : Message object
              The inform message to send.
