Add the NetworkQualityEstimator class that is notified
when net stack receives data.
Expose PeakKbps and FastestRTT Statistics through
GetEstimate() API which may be used by clients like Lo-Fi.
PeakKbps and FastestRTT computation is now
based on prefilter bytes which correctly
represent the amount of data that was transferred
over the wire.
