skvlad 8b45b11144 Revert of Add framerate to VideoSinkWants and ability to signal on overuse (patchset #14 id:250001 of https://codereview.webrtc.org/2716643002/ )
Reason for revert:
Breaks perf tests:
https://build.chromium.org/p/client.webrtc.perf/builders/Win7/builds/1679
https://build.chromium.org/p/client.webrtc.perf/builders/Android32%20Tests%20%28L%20Nexus5%29/builds/2325

Original issue's description:
> Add framerate to VideoSinkWants and ability to signal on overuse
>
> In ViEEncoder, try to reduce framerate instead of resolution if the
> current degradation preference is maintain-resolution rather than
> balanced.
