Enable CI/CD with checkboxes
Description
What if enabling CI/CD were as simple as enabling the checkbox for CI/CD in your project settings (or during new project creation)? So rather than a wizard that configures your CI/CD, you just enable it. If your project has a .gitlab-ci.yml file, then these settings would be disabled as they'd be unnecessary. But if it isn't present, then just use a standard, inferred configuration (based on Herokuish if needed). Beyond tests, we could enable review apps, auto deploy to production, etc.
Bonus points: let people see the generated .gitlab-ci.yml syntax so they can commit to the repo and edit.
