node-mxin: Improve nodes dashboard (#1448) 
* 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.

Node Mixin

This is work in progress. We aim for it to become a good role model for alerts and dashboards eventually, but it is not quite there yet.

The Node Mixin is a set of configurable, reusable, and extensible alerts and dashboards based on the metrics exported by the Node Exporter. The mixin create recording and alerting rules for Prometheus and suitable dashboard descriptions for Grafana.

To use them, you need to have jsonnet (v0.13+) and jb installed. If you have a working Go development environment, it's easiest to run the following:

$ go get github.com/google/go-jsonnet/cmd/jsonnet
$ go get github.com/jsonnet-bundler/jsonnet-bundler/cmd/jb

Note: The make targets lint and fmt need the jsonnetfmt binary, which is currently not included in the Go implementation of jsonnet. For the time being, you have to install the C++ version of jsonnetfmt if you want to use make lint or make fmt.

Next, install the dependencies by running the following command in this directory:

$ jb install

You can then build the Prometheus rules files node_alerts.yaml and node_rules.yaml:

$ make node_alerts.yaml node_rules.yaml

You can also build a directory dashboard_out with the JSON dashboard files for Grafana:

$ make dashboards_out
