fix(prometheus): readd node-exporter and kube-state-metrics support (#9062)

**Description**
Readds both node-exporter and kube-state-metrics.
Also adds the GUI option in SCALE to disable them, in case users want to
run those as seperate charts/apps.

Basically undoes the breakingchange from last time, so users can now
safely update.
