Scrape config:
# Scrape config to crape metrics from more that one container in a Pod
# * `prometheus.io/scrape-container`: Only scrape pods that have a value of `true`
# * `prometheus.io/path`: If the metrics path is not `/metrics` override this. This
# will be the same for every container in the pod that is scraped.
# * this will scrape every container in a pod with `prometheus.io/scrape-container` set to true and the
# port with name `metrics` exists in the container
# * note `prometheus.io/port` is no longer honored. You must name the port(s) to scrape `metrics`
