> While working on KAFKA-13877, I feel it's an overkill to introduce the whole 
> test class as an integration test, since all we need is to just test the 
> assignor itself which could be a unit test. Running this suite with 9+ 
> instances takes long time and is still vulnerable to all kinds of timing 
> based flakiness. A better choice is to reduce it as a unit test, similar to 
> {{HighAvailabilityStreamsPartitionAssignorTest}} that just test the behavior 
> of the assignor itself, rather than creating many instances hence depend on 
> various timing bombs to not explode.
> The scope of this ticket is to refactor the {{RackAwarenessIntegrationTest}} 
> into a {{RackAwarenessStreamsPartitionAssignorTest}}.
