------------------------------------------------------------

[~guozhang] I want to pick it up!

For my comprehension is that we want to expose RockDB stats via Streams metrics 
so that user can use Streams metrics simply to monitor RockDB stats but not to 
access RockDB directly which means `KStream` should be extended.

> RocksDB's own stats can be programmatically exposed via 
> {{Options.statistics()}} and the JNI `Statistics` has indeed implemented many 
> useful settings already. However these stats are not exposed directly via 
> Streams today and hence for any users who wants to get access to them they 
> have to manually interact with the underlying RocksDB directly, not through 
> Streams.
> We should expose such stats via Streams metrics programmatically for users to 
> investigate them without trying to access the rocksDB directly.
