      Description

      HDFS-13946 improved the log for longest read/write lock held time, it's very useful improvement.

      In some condition, we need to locate the detailed call information(user, ip, path, etc.) for longest lock holder, but the default throttle interval(10s) is too long to find the corresponding audit log. I think we should add the timestamp for the longestWriteLockHeldStackTrace
