Apply from a CRD URL?

I'd like to apply from a CRD URL...

Describe the solution you'd like to see

• Like it's usual for the community, URLs can be from git repos that points to a given directory in a given branch
  • See Step 6 from https://docs.aws.amazon.com/eks/latest/userguide/alb-ingress.html
  • It includes parameters of the dir and the label (branch, tag or SHA)

kubectl apply -k "github.com/aws/eks-charts/stable/aws-load-balancer-controller//crds?ref=master

• For this provider, I would expect something very simple:

resource "k8s_manifest" "load_balancer_controller_crds" {
  url   = "github.com/aws/eks-charts/stable/aws-load-balancer-controller//crds?ref=master"
  namespace = kubernetes_service_account.load_balancer_controller.metadata.0.namespace
}

Describe alternatives you've considered

1. Download all the files from the URL to a known directory
2. Execute kubectl apply -k in the dir

That should be possible at least for public http URLs, with the combination of hashicorp/http provider.
Should work as long as each yaml file contain only one resource (See issue #7 for more details).
