KAFKA-3502: move RocksDB options construction to init()
In RocksDBStore, options / wOptions / fOptions are constructed in the
constructor, which needs to be dismissed in the close() call; however in some
tests, the generated topology is not initialized at all, and hence the
corresponding state stores are supposed to not be able to be closed as well
since their `init` function is not called. This could cause the above option
objects to be not released.
This is fixed in this patch to move the logic out of constructor and inside
`init` functions, so that no RocksDB objects will be created in the constructor
only. Also some minor cleanups:
1. In KStreamTestDriver.close(), we lost the logic to close the state
stores but only call `flush`; it is now changed back to call both.
2. Moved the forwarding logic from KStreamTestDriver to
MockProcessorContext to remove the mutual dependency: these functions should
really be in ProcessorContext, not the test driver.
