DB Sanity Test
Summary: @kailiu mentioned on meeting yesterday that we sometimes have trouble opening DB created by old version with the new version. This will be very important to test for column families, since I'm changing disk format for the MANIFEST. I added a tool that can help us test that. Usage: ./db_sanity_test <path> create will create a bunch of DBs under <path> <change RocksDB version> ./db_sanity_test <path> verify will verify consistency of DBs created under <path> Test Plan: ran the db_sanity_test Reviewers: kailiu, dhruba, haobo Reviewed By: kailiu CC: leveldb, kailiu, xjin Differential Revision: https://reviews.facebook.net/D16605
