Remove mutating global state in node-exporter objects

kubelet: Revert label selector

The Kubelet's Service/Endpoints object maintained by the Prometheus
Operator does not have the recommended app label (yet). Therefore we
need to use the old label until a Prometheus Operator version has been
released and integrated in kube-promteheus that does use it.

blackbox-exporter: Prefer ipv4 by default in probe config

blackbox-exporter: Add probe port to Service

node-exporter: do not mount /proc as it is covered by hostPID

jsonnet: add missing labels

install a blackbox-exporter instance
