Rally fails to communicate with Kubernetes cluster

[Juha Kosonen]

When env is created using kubeconfig file ($HOME/.kube/config), the client key and certificates refer to files stored in /tmp. However, these files are removed along with the command execution completion (https://github.com/kubernetes-client/python-base/blob/2d514ce31d9735de91fdfa65981e9d5e7a4476bf/config/kube_config.py#L56), and so an attempt to actually use the env will fail.

bash-4.4# rally env create --from-sysenv --name k8s-tst
