Support Kubernetes 1.6 for Prometheus
Summary
In Kubernetes 1.6, RBAC is now on by default. This means there is now authentication for accessing the kubelet metrics API, which breaks our ability to scan it.
See https://github.com/prometheus/prometheus/issues/2613 for more information.
Steps to reproduce
Set up a cluster on 1.6, install the I2P demo. Connect to Prometheus, view target scrape status.
What is the current bug behavior?
Prometheus will fail to scape the kubelets, receiving a 401 Unauthorized.
What is the expected correct behavior?
Successful scrape.
