[Architecture] Headless mode coming for Chrome...

[Tirloni, Giovanni]

With Firefox 60 and Chrome 66, all tests pass in headless mode for fluid-project/infusion.

If this is all there's to it, we can start migrating CI to headless if people are confident in the new headless features in Chrome/Firefox.
