Reason for revert:
Looks like there's still one failing perf test:
RampUpTest.UpDownUpTransportSequenceNumberPacketLoss
Original issue's description:
> Reland of Periodically update codec bit/frame rate settings. (patchset #1 id:1 of https://codereview.webrtc.org/2923993002/ )

> Reason for revert:
> Create reland cl that we can patch with fix.
