// stats data and a |modifier| to append to each result bucket. For instance, if
// the modifier is '_oneway', the rtt stat will be logged as goog_rtt in
// the video_tx_oneway bucket.
// If |video_codec| is a non-empty string, the codec name is appended last for
// video metrics, e.g. 'video_tx_oneway_VP9'.
