kube-proxy Metrics Exporter

kube-proxy is a critical piece of any Kubernetes cluster, therefore it is highly recommended to gather its metrics. Sometimes (especially in managed clusters) it is not possible to configure kube-proxy to be reachable by Prometheus for metrics scraping, this is why this package exists. Furthermore, this package also adds an authorization layer based on Kubernetes RBAC to the metrics exposed by kube-proxy.
