Matthieu Coudron b9bf757503 kubernetes-helm: support plugins
also introduce helm-s3, helm-diff, helm-secrets plugin.

You can create a wrapped helm with these plugins via:

  myHelm = final.wrapHelm final.kubernetes-helm-unwrapped {
    plugins = with final.kubernetes-helmPlugins; [ helm-s3 helm-secrets helm-diff ];
  };

Running `helm plugin list` will show you these are available.
