This CL is one in a series. To finish the work, the following CLs will be added: 1. CL for connecting RPLR as well 2. CL for RPLR-based FecController 3. CL for allowing experiment-driven configuration of the above (through both field-trials and protobuf) BUG=webrtc:7058 Review-Url: https://codereview.webrtc.org/2638083002 Cr-Commit-Position: refs/heads/master@{#17365}
