#### Summary of Changes
This PR further enables group by operation on storage type in blockstore_rocksdb_cfs metrics.
Such group-by allows us to further compare the performance metrics between rocks-level and
rocks-fifo.
To make things extensible, this PR introduces BlockstoreAdvancedOptions and move shred_storage_type.
All fields in BlockstoreAdvancedOptions will support group-by operation in blockstore_rocksdb_cfs.
