> Currently, the {{JobManagerRunner}} is allowed to shut down itself in case of a job completion. This, however, can cause problems when the {{Dispatcher}} receives a request for a {{JobMaster}}. If the {{Dispatcher}} is not told about the shut down of the {{JobMaster}} then it might still try to send requests to it. This will lead to time outs.
> It would be better to simply let the {{JobManagerRunner}} not shut down itself and defer it to the owner (the {{Dispatcher}}). We can do this by listening on the {{JobManagerRunner#resultFuture}} which is completed by the {{JobManagerRunner}} in case of a successful job completion or a failure. That way we could also get rid of the {{OnCompletionActions}} and the {{FatalErrorHandler}}.
