> Related to https://issues.apache.org/jira/browse/KAFKA-14404
> It's too easy for users to try overriding one of the client configs that Streams hardcodes, and since we just silently ignore it there's no good way for them to tell their config is not being used. Sometimes this may be harmless but in cases like the Producer's partitioner, there could be important application logic that's never being invoked.
> When processing user configs in StreamsConfig, we should check for all these configs and log a warning when any of them have been set
