Part of 10.6 GKE priority issues, https://gitlab.com/gitlab-org/gitlab-ce/issues/42350

How to test

Variations,

• New empty project
• A project with a few files in it
• Visit gitlab-org/gitlab-ce which has a bunch of special files in it like README.MD, LICENSE, etc

When you enable Auto DevOps via project settings -> CI/CD -> General pipelines settings -> Auto DevOps, the "Enable AutoDevOps" button will change to s "Auto DevOps enabled" anchor.

When you add a Kubernetes cluster(see these instructions), the "Add Kubernetes cluster" button will change to a "Kubernetes cluster" (pluralized on EE) anchor.

When you visit those same projects as a normal user, the "Add Kubernetes cluster" button is not visible. "Auto DevOps enabled" anchor is shown when Auto DevOps enabled for a normal user.
