* node-mixin: Improve nodes dashboard
- Use stacking where it makes sense.
- Normalize idle CPU so that stacking is more meaningful.
- Consistently fill where stacking is used but don't fill where not.
- Fix y axis max value for Idle CPU panel.
- Fix y axis min value for memory usage panel.
- Use `$__interval` for range where applicable (and set min step
to 1m).
- Make the right Y axis for disk I/O actually work.
This is just an incremental improvements. It doesn't touch the more
involved TODOs.

empty.

The only deviation that happened so far is to use format="percentunit"
in a Grafana gauge. This change wasn't even properly used in this repo
so far, so I opted to stick with "upstream" for now. If changes are
really needed, we can try to change upstream first.
Another change was done in parallal here and upstream, but it was
"more correct" in upstream. (Change datasource to $datasource
variable, only partially applied here.) Which is another point for
using the upstream and not copy it here.
