Add rate utilization tracker helper class.

This class measures the allocated cumulative byte budget (as specified
by one or more rate updates) and the actual cumulative number of bytes
produced over a sliding window.

A utilization factor (produced bytes / budgeted bytes) is calculated
seen from the first data point timestamp until the last data point
timestamp plus the amount time needed to send that last data point
given no further updates to the rate.

Wireup to EncoderBitrateAdjuster will happen in a follow-up CL.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.

Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.

The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.

Development
