helm: add support for --api-versions

[felixscheinost]

I think including the option in chart2json and the helm module shouldn't cause any issues.

The only thing I am unsure about is whether builtins.map (customType: "${customType.group}/${customType.version}") (builtins.attrValues globalConfig.kubernetes.customTypes) is a good default value or whether some users will run into e.g. infinite recursion using that.

For me it worked fine though. I fetch CRDs using helm and put them into kubernetes.customResources using IFD.

Thanks! Nice fix here; just tested (I had hardcoded a simple fix locally until I could get around to figuring out something better :sweat_smile) and it works for me as well.

Hopefully someone will open an issue in that case but I don't want to block on it.
