      Description

      They expose a new handlerton function and implement within. Percona Server has different implementation for InnoDB. We need to reconcile these.

      See this commit for upstream impementation:
      https://github.com/facebook/mysql-5.6/commit/bcd7646a3c31076c743313dc9608cfa0b6efb1a6 : Supporting START TRANSACTION WITH CONSISTENT [ROCKSDB] SNAPSHOT
      https://github.com/facebook/mysql-5.6/commit/c8b0c7a0b560c54aba913350ecc67f29b2265ea9 : Make START TRANSACTION WITH CONSISTENT ROCKSDB SNAPSHOT read only and use DB::GetSnapshot

      See also MYR-27 which depends on this for mysqldump to be able to dump against MyRocks
