ffbacbccf7 Update node-exporter DaemonSet to fix permission denied 
* Add toleration to run node-exporter on controller nodes
* Add HostToContainer mount propagation and security context group
settings from upstream
* Fix SELinux denied accessing /host/proc/1/mounts. The mounts file
is has an SELinux type attribute init_t, but that won't allow running
the node-exporter binary so we have to use spc_t. This should be more
targeted at just the SELinux issue than making the Pod privileged
* Remove excluded mount points and filesystem types, the defaults are

named `blackbox-exporter`, and use port 8080

a9f9c59b91 Configure Prometheus to allow a custom scrape query param 
* Set `prometheus.io/param` on a Kubernetes Service to scrape
the service endpoints and pass a custom query parameter
* For example, scrape Consul with `?format=prometheus`

```yaml
kind: Service
metadata:
  annotations:
    prometheus.io/scrape: 'true'
    prometheus.io/port: '8500'
    prometheus.io/path: /v1/agent/metrics
    prometheus.io/param: format=prometheus

to scrape kube-scheduler and kube-controller-manager targets
that run on controller(s) with hostNetwork
* Disable the insecure port on kube-scheduler
