Use the kube-native way to construct a client by using the KUBECONFIG env var. That was done in the tests anyway (see the change to the Makefile).
The current system promotes using globvars which is a malpractice that should be avoided. It's only confusing new contributors. Let's remove it and just use the KUBECONFIG variable as in the rest of the Kubernetes ecosystem.
