Detection, sensors and zpool/dataset usage for FreeNAS, TrueNAS (#11474)

It's also possible to do zpool IO from the MIB, but diskIO on LibreNMS makes a lot of assumptions about it coming from the UCD MIB. This changeset adds detection for FreeNAS and TrueNAS - despite having their own enterprise number, the snmpd uses the FreeBSD one. The naming is a bit all over the place, because this reflects reality - IXSystems produce FreeNAS and TrueNAS, the product lines have merged to eliminate FreeNAS, but TrueNAS still calls itself FreeNAS everywhere except the GUI.
