> TrashPolicyDefault clean up Trash based on [UTC|http://www.worldtimeserver.com/current_time_in_UTC.aspx]
currently and the time of cleaning up is 00:00 UTC. when there are large amount of trash data
should be auto-clean, it will block NN for a long time since Global Lock, In the most serious
situations it may lead some cron job submit failure. if add configuration about time of cleaning
up, it will avoid impact on this cron jobs at that default time.
