Improve the message about Auto DevOps/Kubernetes in the empty project page
The new empty project page shows a message about Auto DevOps, useful to users that want to enable it. This also mentions Kubernetes clusters, but it can be improved because they are two independent features (even if strictly related).
We should define the message to show in the following cases:
- Auto DevOps and Kubernetes are both not enabled/configured
- Auto DevOps enabled, Kubernetes not configured
- Auto DevOps and Kubernetes are both enabled/configured
We can consider having the same message for more than one case, if it is the best choice.
