Provide tycho-surefire integration test for JUnit 5 suites

[HeikoKlare]

This is an initial draft for an integration test for using JUnit 5 suites in tycho-surefire.
It is supposed to demonstrate the behavior discussed in

• JUnit 5 Test Suite not working - "No tests found" #2462

@HeikoKlare the referenced issue seems odd, do you maybe want to reference another issue or an issue in a different repository?

Thanks! Yes, sorry for that. I corrected the referenced issue.

To ease investigation of the issue, here is the same test setup with pure Maven surefire: bundle.test.zip
That configuration works fine with test suite as long junit-platform-suite-engine is on the classpath.

@HeikoKlare

is this supposed to fix the mentioned issue:

• Enable JUnit 5 test suite engine in tycho-surefire #2462 #3358

[HeikoKlare]

The test case provided here was only supposed to demonstrate the issue documented in:

• JUnit 5 Test Suite not working - "No tests found" #2462

The test case is also integrated into and thus subsumed by the PR supposed to fix the issue:

• Enable JUnit 5 test suite engine in tycho-surefire #2462 #3358

So in case #3358 gets merged, this becomes obsolete.
