The storage expectations for the RocksDB DB may be different from our usual data

This allows customizing the data directory for the builtin DS storage backend.
Note: if the cluster was already initialized using a directory path, changing that config
will have no effect. This path is currently persisted in mnesia and used when reopening
the DB.
