Split storage box monitoring into new text collector

This was previously monitored as part of the borg text collector, but
now that it only runs after each backup (instead of hourly) the stats
from monitoring.archlinux.org do not remain accurate for long. Switch
back to hourly checks of the storage box's disk usage by adding a new
text collector just for this purpose.
