Update k8s client-go to v6.0.0 (#1340)

* Update k8s client-go to v6.0.0

This fix updates k8s client-go to v6.0.0 as CoreDNS is supported
in 1.9 and v6.0.0 is the recommended version.

There are quite some massive changes that need to be made:
1. k8s.io/client-go/pkg/api/v1 has been changed to k8s.io/api/v1 (repo changed from `client-go` to `api`)
2. kubernetes.Clientset adds one extra layer, so that `kubernetes.Clientset.Services()` and like has been changed to `kubernetes.Clientset.CoreV1().Services()`

Also, we have to stick with specific commits of `k8s.io/apimachinery` and the newly introduced `k8s.io/api`
because go dep still could not figure out the right version to fetch.
