Start/Stop feature (moved from a gh issue)

---

Implement a Start/Stop button in the app view that does the following:

Functionality

When stopping:
Save the current values.yaml of an app and in the background delete that app, but keep it in the app list with the status stopped. Gray out the Stop button when status is stopped.

When starting:
Restore those values while continuing that app again and re-deploy it in the background. Gray out the Start button when status is started.

To-dos

• Save the values.yaml of an app to a database outside of the K8s cluster when stopping an app (so it can be recovered, after the pod has been down)
• Keep the stopped app in the app list and switch its status to stopped
• Pair every values.yaml to the installed apps (is there a unique identifier of an installation?)
• Recover the values.yaml from the database and deploy the stopped app with those values again, switch its status to started

Why

Empower users to adjust relevant parameters and stop and start the apps with their own configuration on-demand to save energy and costs.
