Improve integration tests

[behnazh-w]

The integration tests need to be improved to log debug information more effectively. Also, some of the integration tests that take a long time, e.g., micronaut-core are analyzed with various configurations. We need to pick a different target repository that can be analyzed more quickly with similar configurations.

I think this issue should be closed as we have a new integration test setup now:

• test: add new integration test utility #764
• chore: convert expectation files to policies and use in integration tests #760
