Summary: `git diff origin/6.21.fb origin/6.22.fb -- HISTORY.md` looked odd. This PR fixes it up by moving items from 6.21.0 to 6.22.0 that were never in any 6.21 release. Also mentioned the background stat collection fix under 6.22 (previously it was mentioned under 6.21 patch releases only).

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key-value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it especially suitable for storing multiple terabytes of data in a single database.
