Zeb Hering 0fe728e28a Make the serial port and disk glob per host ...

The shelf moved from iz-pve1 to iz-pve0, which has two SAS HBAs and an
internal backplane that is itself behind an expander. The default
"*-sas-exp*" glob matched all 17 drives there, so the shelf's fans would
have been set from the server's own drive temperatures.

PORT and DISK_GLOB are now overridable from the unit. Documents that the
host holding the shelf also needs the mirror-image DISK_EXCLUDE_PATTERN
in fan_speed.service - it was counting 17 disks until that was set.
