Per the issue with header validation on quic, it's worth trying to run this
against staging to see if it works.  If not we can avoid adding a staging
version of the test to the waterfall.

./run_benchmark --use-live-sites --extra-chrome-proxy-via-header='1.1
Chrome-Compression-Proxy-Testing'
--extra-browser-args='--data-reduction-proxy-experiment=stg'
--browser=android-chrome chrome_proxy_benchmark.quic.smoke

IIUC, --extra-chrome-proxy-via-header only affects the checks for the response
headers.
Using QuIC should only affect the visibility of request headers.
So, I think adding --extra-chrome-proxy-via-header='1.1
