Subject: [PATCH] Improve kubernetes package to handle deployment from url

When I was working on ArgoCD test integration, I found
that to expose ArgoCD server, we need to add `ingress`
to expose an endpoint.

To do it with Kind, it's necessary to apply a custom yaml
available on Github. It simply then need `kubectl apply -f <url>`
