.`RocksDB` now replaces `levelDB`
This update changes the default back end for the `omap` database from the `levelDB` to the `RocksDB` database. `RocksDB` uses the multi-threading mechanism in compaction so that it better handles the situation when the `omap` directories become very large (more than 40 G). `LevelDB` compaction takes a lot of time in such a situation and causes OSDs to time out.
