> Currently, the different runners for the Flip-6 components {{JobMaster}}, {{ResourceManager}}
and {{TaskExecutor}} don't wait until the component has been shut down in their own {{shutDown}}
method. The problem is that the {{AkkaRpcService}} implements the {{RpcService#shutDown}}
method via a {{PoisonPill}} which is not executed synchronously. Instead we should obtain
the {{RpcEndpoint#getTerminationFutures}} and wait on the returned future (with a given timeout).
