> Modify the LogDeletionService to support Log aggregation for LRS

> Currently, AggregatedLogDeletionService will delete old logs from HDFS. It
> will check the cut-off-time, if all logs for this application is older than
> this cut-off-time. The app-log-dir from HDFS will be deleted. This will not
> work for LRS. We expect a LRS application can keep running for a long time.
> Two different scenarios:
> 1) If we configured the rollingIntervalSeconds, the new log file will be
> always uploaded to HDFS. The number of log files for this application will
> become larger and larger. And there is no log files will be deleted.
> 2) If we did not configure the rollingIntervalSeconds, the log file can only
> be uploaded to HDFS after the application is finished. It is very possible
> that the logs are uploaded after the cut-off-time. It will cause problem
> because at that time the app-log-dir for this application in HDFS has been
> deleted.
