Summary: Add API to WriteBatch to store range deletions in its buffer which are later added to memtable. In the WriteBatch buffer, a range deletion is encoded as "<optype><CF ID (optional)><begin key><end key>". With this diff, the range tombstones are stored inline with the data in the memtable. It's useful for now because the test cases rely on the data being accessible via memtable. My next step is to store range tombstones in a separate area in the memtable. Test Plan: unit tests Reviewers: IslamAbdelRahman, sdong, wanning Reviewed By: wanning Subscribers: andrewkr, dhruba, leveldb Differential Revision: https://reviews.facebook.net/D61401
