Copy diff package from argoproj

Kubernetes hasn't been updated in argoproj.
The files have been copied and import paths have been adapted.

Since argo-cd and gitops-engine use the server scheme from
k8s.io/kubernetes we need to work around 'unknown revision 0.0.0'
errors, by including replace statements in the go.mod file.

kubernetes/issues/79384

Vendoring the argoproj files helps with updating k8s, but is not enough
to get rid of the replace statements.
