Add a ScrapeConfig for node-exporter job using GCE discovery for all VMs that aren't a kube node
Split form #2623 (closed)
As part of our goal to scrape the same Prometheus jobs that the VMs do from the Prometheus remote agents, we can start with the node-exporter jobs, as every VM's regardless of the service label, should have the node-exporter running.
This issue will be about add the relevant ScrapeConfig
using the GCE discovery to scrape the node exporter across all VM's that aren't kubernetes.
