Docker version of visualmetrics This makes it easier to run visualmetrics to collect timing metrics from a video of a page loading. This will help us for T115857 and T114425 because we can record a video locally and get waterfall graphs from Firefox and metrics from the video. Hopefully this can also help us get some sane values for proxy browsers.
