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

Browse Source 
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.
