Description

In Kafka Streams, we move from old metrics to new metrics, and added a config for users to explicitly opt into using the new metric.

While we did remove old metric in the code base completely, we kept the config (what is desired, as if we make a similar change in the future the config would just be there), however, there is still code left which still uses the config for no good reason (especially test code).

It might be worth to cleanup a little bit.
