* CoordinatedShutdown that can run tasks for configured phases in order (DAG) * coordinate handover/shutdown of singleton with cluster exiting/shutdown * phase config obj with depends-on list * integrate graceful leaving of sharding in coordinated shutdown * add timeout and recover * add some missing artery ports to tests * leave via CoordinatedShutdown.run * optionally exit-jvm in last phase * run via jvm shutdown hook * send ExitingConfirmed to leader before shutdown of Exiting to not have to wait for failure detector to mark it as unreachable before removing * the unreachable signal is still kept as a safe guard if message is lost or leader dies * PhaseClusterExiting vs MemberExited in ClusterSingletonManager * terminate ActorSystem when cluster shutdown (via Down) * add more predefined and custom phases * reference documentation * migration guide * problem when the leader order was sys2, sys1, sys3, then sys3 could not perform it's duties and move Leving sys1 to Exiting because it was observing sys1 as unreachable * exclude Leaving with exitingConfirmed from convergence condidtion
