I like the idea to use `ReceiveTimeout` messages to detect blocked
`JobManager`. I think the timeout should be configurable via the
`flink-conf.yaml` file. Thus, you either pass the `Configuration` to the
`JobClientActor` or the individual timeouts. If written some remarks concerning
the different state handlings.
> Make the JobClientActor check periodically if the submitted Job is still
> running and if the JobManager is still alive

> 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.
