Accept a connection.  The bind listener will be called when the channel is bound; the open listener will be called
when the connection is accepted.  It is not guaranteed that the open listener will be called after the bind listener.

Params:
  • openListener – the listener which will be notified when the channel is open, or null for none
  • bindListener – the listener which will be notified when the channel is bound locally, or null for none
Returns:the future connection
