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
