    Updated this PR. The test that should be extended is the last open question if I did not

>                 URL: https://issues.apache.org/jira/browse/FLINK-2111
>             Project: Flink
>          Issue Type: Improvement
>          Components: Distributed Runtime, JobManager, Local Runtime, Streaming, TaskManager,
>            Reporter: Matthias J. Sax
>            Assignee: Matthias J. Sax
>            Priority: Minor
> 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
