Liviu Rau b3477fdd01 [test] Refactor testrunner (4)
- Removed duplication and unnecessary indirection from all suites testcfgs.
 - Introduced a more comprehensive context to cover both command context and other platform specific concerns.
 - Propagated above context to TestLoader to allow for test counting command execution on all platforms.
 - Wrapped original pool with another class to give it a new interface and allow injecting different implementations in the future.
 - Consolidated progress indicators under a single processor in the pipeline.
 - Consolidated result retention requirements calculation outside of pipeline chain.
 - Refactored LoaderProc and got it under tests.
 - Added some more tests for the standard runner.
 - Extracted BuildConfig class.
