This role installs Prometheus' Node exporter on Linux hosts, and configures a systemd unit file so the service can run and be controlled by systemd.
Note: If you're running in a Kubernetes cluster, you could run Node exporter as a DaemonSet in the cluster, instead of installing it on individual nodes.
