LXD metrics with Prometheus and Grafana

Ever since version 4.19, LXD has had support for instance metrics through a new API meant to integrate with Prometheus or similar time series databases.

In this video, we'll be going over the new LXD feature, go over installing both Prometheus and Grafana, then import the official Grafana dashboard for LXD and finally go over some of the metrics in the dashboard.

It would be great if all the commands could be put in the description so some of us with impaired vision could copy n paste them.
