Control capybara headless mode for testing via environment variable

[Philwi]

What? Why?

For developer convenience I want to run the headfull capybara mode without changing the configuration file all the time. I just want to control it with an environment variable to turn it on if I need to see what happens inside the browser.

What should we test?

• It is only for the test environment
• run HEADLESS=false bundle exec rails rspec spec/system/**
• browser will open and executing the system tests

I've tested, and it's working!

• HEADLESS=true bundle exec rspec spec/system/admin/enterprise_groups_spec.rb:27 run the spec in the headless mode (ie. doesn't trigger any browser window)
• HEADLESS=false bundle exec rspec spec/system/admin/enterprise_groups_spec.rb:27 run the spec with head mode (ie. does trigger the default (?) browser window)

Merging! 🎉

Thanks! 🙏
