SAMZA-1802: Enable host affinity when RocksDB is present

[weisong44]

We should enable host affinity when RocksDB table is present, this should be done in RocksDB table provider.

Thanks!

Ideally we should be doing this at a much higher level where if we detect a stateful job, enable host affinity. Is there a specific reason for this inconsistency between table and native store?

After discussion we will first enable host affinity in RocksDB table provider, and later this may be done for all RocksDB stores at a central place.
