sdv-image-minimal missing SDV edge components

[mikehaller]

Describe the bug The sdv-image-minimal image should contain the minimal SDV.EDGE core components. Compare to sdv-image-full, which contains additional developer tooling and convenient tools, the minimal image should showcase the minimum size for a "production" setup which still offers all of the features on a service level (e.g. for OTA Updates, cloud-connector and self-update-agent etc.)

To Reproduce Steps to reproduce the behaviour:

1. Boot the second partition "SDV Minimal"
2. Check sdv-health or manually like systemctl status kanto-cm

Expected behaviour

• Required services are installed and running
• sdv-health shows all the required services and required containers as up and running
  • Service: containerd
  • Service: mosquitto
  • Service: kanto-cm
  • Service: rauc
  • cloud-connector
• Optional services and optional containers are shown as WARNING and are not installed on the image (to save disk space on rootfs)
• Note: actually, sdv-health should not even be installed on the rootfs of sdv-image-minimal
• Note: sshd is discussable, i suggest to have it installed on the minimal image for troubleshooting purposes for now.

Leda Version (please complete the following information):

• Version: 2022 0.0.3
• Machine: qemux86_64

Additional context Add any other context about the problem here.

Actually, bash and sdv-health should not even be on the minimal image.

We may even evaluate to replace systemd on the minimal image, but that requires more conceptual work (may be a completely different configuration, not sure if we can do that using a single distro).
