Browse source 
* properly shutdown ArteryTransport using CoordinatedShutdown, #22671

* The shutdownHook changed hasBeenShutdown flag to true, and then when
  the transport.shutdown was invoked the shutdown sequence was ignored
  until it was too late, ActorSystem already terminated.
* Also improved the cluster shutdown tasks when the cluster node had not
  joined

* CoordinatedShutdownLeave explicit events
