    The file was added by @StephanEwen -- it got updated when I ran `gulp` so I just committed
the changes. To me, it would make sense to remove the file -- not sure why it is there...
(maybe we should .gitignore it after removal)

> Currently, streaming jobs can only be stopped using "cancel" command, what is a "hard"
stop with no clean shutdown.
> The new introduced "stop" signal, will only affect streaming source tasks such that the
sources can stop emitting data and shutdown cleanly, resulting in a clean shutdown of the
whole streaming job.
> This feature is a pre-requirment for https://issues.apache.org/jira/browse/FLINK-1929
