Profit from the default cAdvisor deployed by k8s to deploy the
remaining monitoring stack on top, made of node-exporter,
Prometheus and Grafana.
Node-exporter is ran as a normal pod through a manifest, while
Prometheus and Grafana are deployments with 1 replica.
Prometheus has compliance with Kubernetes, so the discovery of
the nodes and other k8s components is configured directly in
Prometheus configuration.
