Make auto deploy "zero click" configuration
Description
Auto deploy is awesome (if somewhat limited), but is buried behind a button that only shows up if you've already configured a Kubernetes service for the project. We can remove the special casing and make auto deploy just another .gitlab-ci.yml
template, which simplifies code, but buries it even further. @sytses suggested selecting auto deploy by default from the template list, which is an interesting idea, but it feels weird to special-case it like that. We want auto deploy to be really easy to enable, but going further, what can we do to make it literally "zero clicks" to enable? e.g. every new project has auto deploy enabled by default, with testing, CI, and CD.
