Enable atomic bulk loading

Upstream commit ID : fb-mysql-5.6.35/269d05b0beb761d9f9ba057f12b62b0077a3c4a2
PS-6864 : Merge fb-prod201902

Summary:
Enable atomic bulk loading - bulk loading using SST APIs are now atomic.
You should not observe any in between state if there is any failures in
ingestion (there are some caveats, as usual, that needs to be
investigated/documented).

This change essentially delays all SST ingestion until finish_bulk_load,
and ingest them all in one batch. Care is taken to:
1. Make sure the state management of multiple `Rdb_sst_info` are done
transactionally as well to match the ingestion,
2. Works well with closing connections and ALTER TABLE statement race
conditions (however under race conditions the ingestion are forcefully
interrupted and therefore no longer truly atomic - this needs to be
investigated to see if there are other approaches).
3. Files are properly cleaned up in the failure case

NOTE: I specifically avoided doing refactoring in order to make code
review easier. Finish_bulk_load is becoming too big and that will get
addressed later.

This changes takes advantage of latest
[PR][(facebook/rocksdb#4895) from Yanqin Jin
which supports ingesting SST from multiple column families.

NOTE: This change updates rocksdb to latest commit in the PR and will
update to the proper rocksdb version once the PR is merged and we've
decided on a proper RocksDB version to consume.
