Update officially supported client libraries

[drubin]

Update officially supported client libraries to match ones listed https://kubernetes.io/docs/reference/using-api/client-libraries/#officially-supported-kubernetes-client-libraries

I was browsing and it was confusing that we listed only 2 of the supported libraries.

I think it makes sense to list them all or just link to the official list located at https://kubernetes.io/docs/reference/using-api/client-libraries/#officially-supported-kubernetes-client-libraries

I would be happy to update the docs either way?

@drubin You'll need to rebase to fix a build issue that snuck into the master branch. Once the build tests pass and I check the preview, we can merge this. LGTM

[drubin]

@chenopis Rebased. Hopefully, the tests pass.

If you need anything else updated let me know.
