:unicorn: Add Certificate data as outputs

[martin31821]

:fire: What happened?

Provisioned k3s cluster, tried to bootstrap k8s terraform provider with the outputs of this module, but theres no way to directly set the kubeconfig.

:+1: What did you expect to happen?

I'd like to add three outputs: Cluster-CA Pem, User Certificate and User Key, to bootstrap the k8s provider.

:mag: How can we reproduce the issue?

• Create TF state
• Try to create a k8s provider that's running against the k3s
• No way to do it.
