Try more k8s deployments

We were using k8s to deploy AiiDAlab to MarketPlace and using microk8s recipe for internal THEOS/PSI deployments.
We also have k8s recipes to do it. The k8s is the production way to have a robust deployment, so we need to bring it back and make it more generic in the future.
Check this topic along with A demo instance on Azure using the K8S recipes which share the common configurations.
