Description

In case that the JobManager dies without notifying possibly connected JobClientActors or if the job execution finishes without sending the SerializedJobExecutionResult back to the JobClientActor, it might happen that a JobClient.submitJobAndWait never returns.

I propose to let the JobClientActor periodically check whether the JobManager is still alive and whether the submitted job is still running. If not, then the JobClientActor should return an exception to complete the waiting future.
