For quic loss detection, replace quicconnectionstats.total_loss_detection_time by quicconnectionstats. total_loss_detection_response_time to improve the accuracy of detection speed. protected by existing --gfe2_reloadable_flag_quic_enable_loss_detection_experiment_at_gfe. On skmobile-cjj5 this reduced the threshold value from 8 to 4.5: http://shortn/_vT0AbUjKU6. shift value did not change.
