HDDS-15749. Run specific JUnit tests if possible

[adoroszlai]

What changes were proposed in this pull request?

If only JUnit test classes have changed, limit tests run in pull request CI to that set. This adds a new check specific-tests (with display name integration), which is the same as integration, but only runs specific tests instead of profiles in a matrix.

Example: f5a5f0f only changed TestContainerBalancerDatanodeNodeLimit, no need to run all other integration tests.

Counterexample: 10a9437 changed test helper code (AbstractOzoneManagerHATest and MiniOzoneHAClusterImpl), need to run all integration tests.

Note: there are many test helpers and parent classes that do not follow naming convention. We'll need to rename these to ensure proper coverage. Creating as draft until we address that.
