Change in API för components

[rogermartensson]

Thanks for this check.

I'm trying to extend with more components (more api-resources) to check on and see a need for a change in the api.

The need I had was to add some checks on some resources for cert-manager.io. This does not work with your current implementation.
I had to change in the mapping file and an addition to build_url to supply the apiResource-name.

My understanding is that the URL for a CRD is "server:someport/apis/".
so for some CRDs in cert-manager.io it uses apiResource-name "cert-manager.io/v1" and the url becomes "server:someport/apis/cert-manager.io/v1".

I don't know from which version of kubernetes this is used but it could be possible to remove the is_core value in mappings. Unless you want to support the older URL.

If I find the time I may be able to send a PR but this is pretty simple changes of the mappings file and it's usage.
