Simha Venkataramaiah 60bf2b7d4a Add APIs to query SST file metadata and to delete specific SST files ... Summary: An api to query the level, key ranges, size etc for each SST file and an api to delete a specific file from the db and all associated state in the bookkeeping datastructures. Notes: Editing the manifest version does not release the obsolete files right away. However deleting the file directly will mess up the iterator. We may need a more aggressive/timely file deletion api. I have used std::unique_ptr - will switch to boost:: since this is external. thoughts? Unit test is fragile right now as it expects the compaction at certain levels.
