[Architecture] Headless mode coming for Chrome...

[Tirloni, Giovanni]

Hello,

I'm proposing we switch infusion's CI tests to use containers and headless browsers:

   https://github.com/fluid-project/infusion/pull/909

I'd like to thank Tony for his work on enabling headless browsers in gpii-testem. It made everything easier while working on this.

All feedback is welcome!

Cheers,
Giovanni
