Remove k8s package

[phillebaba]

Describe what should be investigated or refactored

The k8s package with exception for a couple of functions simply wraps a Kubernetes clientset with very little value add. The functions return structs from k8s api package so the current implementation does not decouple the dependency towards these packages. This just increases bloat and complexity without any functionality. I suggest that we remove the k8s package and instead export a clientset in the Cluster struct. Allowing the calling code to use the clientset directly.
