> At this moment, every raft group creates RocksDBLogStorage which, in turn, 
> creates an instance of RocksDB without sharing resources with other log 
> storages. This inflicts memory overhead and leads to out of memory killer 
> killing process on TeamCity.
> We need to use one rocksdb instance for all log storages
