Test Helm remote repo

[jguionnet]

Describe the solution you'd like I would like the helm test feature to support the --repo options, I would like that underneath the following commands could be executed

helm template keda --namespace medieval-38bl76 --set metricsServer.replicaCount=45 --set resources.metricServer.limits.memory=4545Mi --repo https://kedacore.github.io/charts

helm template --namespace keda-system keda -f custom-values.yaml --repo https://kedacore.github.io/charts

I want to verify that my customization on top of chart work from release to release of remote chart I am using

Describe alternatives you've considered

Why not add the Helm repo and reference like so?

$ helm repo add kedacore https://kedacore.github.io/charts
$ helm template keda kedacore/keda --namespace keda --version 2.12.0

$ helm template keda kedacore/keda --namespace keda --version 2.12.0

I could and how do I do that programmatically with terratest?

    options := &helm.Options{}
    helm.AddRepo(t, options, "keda", "https://kedacore.github.io/charts")
    helm.RunHelmCommandAndGetOutputE(t, options, "repo", "update")
    helm.RunHelmCommandAndGetStdOutE(t, options, "template", "keda", "kedacore/keda", "--namespace", "keda", "--version", "2.12.0")

I was thinking you could also use helm.RenderTemplateE(), but I see that it expects a local chart directory unlike the respective helm template command.
