Problem Statement

The generated k8s manfiests use labels like service and app, they seem to be commonly used, but not official. Also the current setup creates a view in cilium hubble like this:

Proposed Solution

K8s has a set of "recommended labels" which are also supported by a variety of tools (e.g. cilium), we should use them instead of app or service.

The recommended labels are listed here: https://kubernetes.io/docs/concepts/overview/working-with-objects/common-labels/

So we could do something like the following defaults

metadata:
  labels:
    app.kubernetes.io/name: <name of the service, database, loader>
    app.kubernetes.io/instance: <name of the service, database, loader>-<randomly generated id>
    app.kubernetes.io/version: <version of the used image>
    app.kubernetes.io/component: <service or database or loader>
    app.kubernetes.io/part-of: <default to ApplicationSimulator>

Additionally we allow them to be overwritten by the user.
