Review comment:
Log would be too much, I think we should avoid debug log in normal code path.

> When a streaming job run for a long time, the amount of logs may be very
> large. The current WebUI shows all content of logs. It will cost much time to
> download logs from task managers. and the browser cannot display the logs.
> Therefore, I suggest that Flink uses DailyRollingAppender to split logs by
> default, and task manager provides an API that can get logs based on a
> parameter of time interval. In this way WebUI can display logs based on time
> interval.
