On top of #1662 and 2nd part of #1657 . Ignore commits before Respect ClassName and MethodName filters in TestNG runner.. (Didn't want to make a PR into that branch because the semantics become confusing, and no one will see a PR from our fork into our fork anyway.)
We now correctly handle test selectors in TestNG.
Also, we do some minor refactoring, removing TestNGWrapper and the "TmpSuite" xml suite.
Test plan: test in TestNGIntegrationTest.
