KAFKA-20689: Migrate reset integration tests to ClusterInstance

[Russole]

Migrate the reset integration tests in the tools module to use
ClusterInstance.

The tools module previously depended on Streams integration test
utilities through test outputs. Those utilities still use Hamcrest, so
removing the explicit Hamcrest runtime dependency from tools exposed
an indirect runtime dependency.

Instead of changing IntegrationTestUtils, this patch updates
ResetIntegrationTest and ResetIntegrationWithSslTest to use the
Kafka common test cluster framework directly. The reset tests now keep
local copies of the small subset of test utility behavior they need,
staying as close as possible to the original IntegrationTestUtils and
EmbeddedKafkaCluster semantics while removing the dependency from
tools.

This allows the unnecessary Hamcrest test runtime dependency to be
removed from the tools module.

Would you mind removing those unrelated changes?

[Russole]

Thanks @chia7712 for the review. I can remove the IntegrationTestUtils changes.

One thing I noticed locally is that if I revert those changes but still remove Hamcrest from tools, :tools:test fails with NoClassDefFoundError: org/hamcrest/Matchers.

So even though tools does not use Hamcrest directly, some tools tests call IntegrationTestUtils from the Streams integration tests, and that class still uses Hamcrest. That means tools still needs Hamcrest indirectly unless we also remove the Hamcrest usage there.

For example, these tests fail after reverting the IntegrationTestUtils change:

• ResetIntegrationWithSslTest.testReprocessingFromScratchAfterResetWithIntermediateInternalTopic
• ResetIntegrationWithSslTest.testReprocessingFromScratchAfterResetWithIntermediateUserTopic
• ResetIntegrationWithSslTest.testReprocessingFromScratchAfterResetWithoutIntermediateUserTopic
• ResetIntegrationWithSslTest.testResetWhenInternalTopicsAreSpecified

Do you prefer that I keep the IntegrationTestUtils change in this PR, or should I leave the tools Hamcrest dependency as-is?

[chia7712]

Could we rewrite both ResetIntegrationTest and ResetIntegrationWithSslTest using ClusterInstance?

[Russole]

Yes, that makes sense. I’ll look into migrating ResetIntegrationTest and ResetIntegrationWithSslTest to ClusterInstance so we can keep the dependency cleanup scoped to tools instead of changing IntegrationTestUtils.
