KAFKA-8262, KAFKA-8263: Fix flaky test `MetricsIntegrationTest` (#6922) 

- Timeout occurred due to initial slow rebalancing.
- Added code to wait until `KafkaStreams` instance is in state RUNNING to check registration of metrics and in state NOT_RUNNING to check deregistration of metrics.
- I removed all other wait conditions, because they are not needed if `KafkaStreams` instance is in the right state.
