Alistair Coles e572938af3 Use headless option for cors functional test runner
Some selenium webdrivers (e.g. Chrome, Firefox) support a headless
option so we can expose that as an option for the test runner too.

Use this in an attempt to fix "Error: cannot open display: :99" errors
seen in the gate.

setup - Create several test containers with well-known names, set appropriate

run - Use Selenium to load the website, wait for and scrape the results,
