Research Task: Replace RegistryCreds Chart with Kyverno Policy

[victorgetz]

Maybe it is possible to replace RegistryCreds with this:

• https://kyverno.io/policies/other/add-imagepullsecrets-for-containers-and-initcontainers/add-imagepullsecrets-for-containers-and-initcontainers/
• https://kyverno.io/policies/other/sync-secrets/sync-secrets/

But be careful about ArgoCD and if it triggers a diff or not

We switched to kyverno. We deprecated registry-creds here #56
