Description

Since FLINK-3427 is done, there's no need to have the following doc in https://ci.apache.org/projects/flink/flink-docs-release-1.3/monitoring/debugging_event_time.html#monitoring-current-event-time

"There are plans (see FLINK-3427) to show the current low watermark for each operator in the Flink web interface.

Until this feature is implemented the current low watermark for each task can be accessed through the metrics system."

We can replace it with something like "Low watermarks of each task can be accessed either from Flink web interface or Flink metric system."
