Summary:
- Add support for RocksDB engine (developed as a drop in replacement for innodb) to hgsql to allow new xdb.hgsql.1-10 shards to host hg repos
- Prefer MySQL test DBs in same region
- Run all hgsql unit tests also for RocksDB engine
- Allow for nested ifs to make that possible (downside if you switch off rockdb tests, innodb tests are run twice)
