raid: add a new "raid" fact
This holds a array of all the possible RAID configurations that can be
found in one server. Hence, it will support configurations such as
software RAID on top or on the side of hardware RAID, or multiple RAID
controllers in one server.
Unused for now -- it's still useful to populate the database with it, so
that errors can be found before we can start using it.
