Move cloud-logging from JUnit4 to JUnit5
creating this as a draft-PR first as I have quite a lot to comment what I did in this PR.
Nevertheless: NO PROD CODE got CHANGED. ONLY TESTS and maven dependencies. This PR mitigates technical debt and does NOT add any functionality.
@aamotharald: Note, that the JUnit 4->5 migration was part of #173 for the release-4 branch.
:-) I think I have learned a lot doing the same thing again. So I'll just check how you solved some issues that I had.. Cheers, Harald
This PR is now obsolete. The main branch uses JUnit 5. This is because the old main branch is now called release-3. If you want to contribute this change to the old version, please recreate this PR.
