This doesn't actually make the tests run on canary, it just adds an option to
run on canary. Is it okay to submit and figure out when to run on which channel
in a follow up?

Currently, the tests run with whatever browser is installed locally if you run
them locally, and with stable if you run them on the buildbots. On the
buildbots, I think we want to run once on stable and once on canary. But I'm not
sure what we want to do for local development?

Current plan is to submit this CL, and then update the recipe in
https://codereview.chromium.org/1428713006

I don't yet have a plan to change the local dev_server scripts--they currently
use the locally installed Chrome.
