Summary: Add a function to return the perf level. It is to allow a wrapper of DB to increase the perf level and restore the original perf level after finishing the function call. Test Plan: Add a verification in db_test Reviewers: yhchiang, igor, ljin Reviewed By: ljin Subscribers: xjin, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D19551
