> Currently, the "currentLowWatermark" metric is only reported in {{StreamInputProcessor}}
(and the two-input version). This means that watermarks are only reported for operators directly
after a shuffle.
> We should report the watermark in all operators (including sources), so that users can
better diagnose problems with watermarks.
