Introduce possibility to poll stats and notify analyzers.
This CL introduces the possibility to poll the 2 peer connections

It also introduces a dummy AudioQualityAnalyzer that will have to
be implemented in a follow-up CL and it moves every type of the
test framework inside the webrtc::test namespace.
