How has this code been tested

This is currently not possible to compile because github.com/argoproj/argo-cd/v2 uses an older version of k8s.io/client-go that breaks with the one that is used in github.com/crossplane/crossplane-runtime.

i know ;) thats why its a draft - but with this branch we can use provider-argocd in functions

[janwillies]

should be argocd

I think if that will be merged, the crossplane-runtime update should work quite well. All the replace's in the mod-file could be removed…

I have made the code compile by replacing github.com/argoproj/gitops-engine with asaf-erlich/gitops-engine@1c9f565 which is the WIP in argoproj/gitops-engine#565.

Since we are not using the gitops-engine itself and only use the API types I think it is safe to merge this.

LGTM. I fixed the remaining issues myself. Thanks a lot @haarchri!
