Making ZFS ARC Grafana Panels FreeBSD-Compatible

Steps taken to make an imported ZFS/Grafana dashboard work correctly on FreeBSD. Panels assumed Linux exporters and referenced metrics that do not exist on FreeBSD. The result was a dashboard full of empty panels. This walkthrough shows how the missing ARC kstats where identified, cleanly exported and refactored so that the panels reflect the real FreeBSD kernel state.
