> This task comes after FLINK-5017, which adds the new element {{StreamStatus}} to be incorporated with watermark progression logic.
> This task tracks the implementation of source idleness awareness and status toggling in {{SourceFunction.SourceContext}}s.
> The source contexts should work on an "idle interval", where we determine the containing {{SourceStreamTask}} to be idle if no new records / watermarks have been collected in-between 2 continuous checks. (default value is 0. Letting this value be user configurable is tracked by FLINK-5018).
