Jonas Oreland 80c87d7151 RtpEncodingParameters::request_resolution patch 2
This cl/ implements configuring of encode resolution
in the video_stream_encoder (webrtc_video_engine) in
a way that is independent of frame resolution (i.e
not using scale_resolution_down_by).

The cl/ reuses the VideoAdapter as is, and hence
the output resolution will be the same as it is today.

Anticipated further patches
3) Hook up resource adaptation
4) Let VideoSource do adaption if possible
