I really hope upstream node_exporter is happy adding new exports!

Still slowly hacking on my homelab Prometheus bringup, but I've already got a start developing a battery level/power supply exporter. By far the most important Node information I want metrics and alarms on in my developer life! https://github.com/rektide/node_exporter/tree/export-battery

Almost went with a standalone Node exporter, but I decided I'd try some Go, and tour some of the Prometheus codebase. MustNewConstMetric is a very confusing thing to me, but hopefully I'm on the right track! Feeling double-inspired to get my homelab Prometheus up and going right now, between renewed excitement for these exporters and the 1.0! So close!

If the interface you're getting the metrics from is generic and standardized enough to work on most Linux systems, it has a good chance of making it in. "/sys/class/power_supply/..." probably fits that requirement, but bbrazil (same name on GitHub) would be the best to give a final judgement on that kind of thing.

Ah sorry, he is "brian-brazil" on GitHub.
