Description

We should add an integration test for Kafka Streams, that validates:

1. After streams application are started, all metrics from different levels (thread, task, processor, store, cache) are correctly created and displaying recorded values.

2. When streams application are shutdown, all metrics are correctly de-registered and removed.
