A revert of this CL (patchset #1 id:1) has been created in
https://codereview.webrtc.org/2588743002/ by kthelgason@webrtc.org.

The reason for reverting is: Bug affecting perf tests has been fixed. The issue
was that I had accidentally disabled cpu overuse adaptation based on the
encoders ScalingSettings, not just quality-based scaling..
