Introduce base test classes to share thread scope annotations

Currently we run unittests with clusters running in the background
that can potentiallly spawn threads causeing the thread leak control
to fire off in tests that don't use the test cluster. This commit
introduces some base classes for that purpose shadowning lucene test
framework classes adding the approriate ThreadScope.
