shows jm/tm logs more friendly.

> About the test, I don't find any tests for the REST API of logs. Should I
add tests for `JobManagerLogFileHandler`, `JobManagerLogListHandler`,
`TaskManagerLogListHandler ` and `TaskManagerLogFileHandler `?
Yes, you should add some unit tests to make sure the basic logic is right.
Some old codes may not be covered well by testing. However the newer codes are
covered quite well. We should keep this good habit.

> 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.
