chore: Parallelize Tests

[rahulsom]

This will use all available cores to run tests, and parallelize by all - suite/class/method. On machines with multiple cores, this will vastly improve test performance. These times are on my M1 MBP with 10 (8P + 2E) cores. They were reported by maven on running mvn verify.

I first ran mvn verify and ignored the time.
Then I ran it thrice without this change, and thrice with this change.

All times in seconds.

	Run 1	Run 2	Run 3	Average
Before	519	516	519	518
After	123	124	124	124
Savings				394
%				76

Testing done

All existing tests pass

Submitter checklist

Beta Give feedback

1. Make sure you are opening from a topic/feature/bugfix branch (right side) and not your main branch!
2. Ensure that the pull request title represents the desired changelog entry
3. Please describe what you did
4. Link to relevant issues in GitHub or Jira
5. Link to relevant pull requests, esp. upstream and downstream changes
6. Ensure you have provided tests - that demonstrates feature works or fixes the issue

The test failure is somewhat legit. Running too many tests in parallel on lower end hardware/vm will cause timing issues and make com.sonyericsson.jenkins.plugins.bfa.model.FailureReaderTest.testScanOneFileWithLineTimeout flaky.
