### Summary This PR cleans up `ListConsumerGroupTest` and avoids starting a cluster for tests that only validate argument parsing or string parsing logic. The main changes are: - Remove the class-level `@ClusterTestDefaults` and apply the cluster configuration only to tests that require a real cluster. - Convert `testListWithUnrecognizedNewConsumerOption` to a plain `@Test`, since it only verifies that `--new-consumer` is rejected by `ConsumerGroupCommandOptions.fromArgs`. - Pass `ClusterInstance` explicitly to cluster-backed helper methods instead of keeping it as test class state. - Merge the package-private `ListConsumerGroupUnitTest` into `ListConsumerGroupTest`, so the file contains a single test class. - Remove the old `set(...)` helper and use typed `Set` / `HashSet` directly while keeping the surrounding test style consistent with nearby Kafka tests. ### Testing Passed: ```bash ./gradlew :tools:test --tests org.apache.kafka.tools.consumer.group.ListConsumerGroupTest -- This is an automated message from the Apache Git Service.
