Create Docker container (for all users), and a k8s helm (for EDITO)

Now that we have Autosubmit in Docker, it would be great to have the other parts of AS in Docker too, including API and the GUI.

Besides, we will need it for EDITO. In EDITO we also have to create a k8s helm chart for the Autosubmit GUI. The EDITO Infra team created a tutorial on how to do it, and shared an example web app helm that can be used as reference (that should save us a lot of time):
