RocksDB has an option to optimize Bloom Filter that minimizes internal memory

The feature's been production ready since v6.22.0. According to RocksDB release
note, v9.2.0 and above, this flag is enabled by default. It is said to reduce
memory footprint by 10%.

We should either bump RocksDB version or enable this feature flag in our
current version.
