8017fd8eb9 Increase default scrub threshold from 30 days to 5 weeks. Using 
whole weeks makes it easier to predicate when the scrub would
happen.

16c4413fa6 This script parses output of userland tools. In the case of a faulted 
zpool the output causes the script to bail out with syntax errors.
Since a scrub of a faulted zpool is pointless, just skip over any pools
marked as such.

63669de232 Add a periodic zfs scrub script. 
Features:
 - configurable amount of days between scrubs (default value or per pool)
 - do not scrub directly after pool creation (respects the configured
   number of days between scrubs)
 - do not scrub if a scrub is in progress
 - tells how to see the status of the scrub
 - tells how many days since the last scrub if it skips the scrubbing
 - warns if a non-existent pool is specified explicitely
   (default: no pools specified -> all currently imported pools are
   handled)
 - runs late in the periodic run to not slow down the other periodic daily
   scripts
