Cron scripts too chatty, need "--quiet" option.

[steveg@…]

Some of the cron scripts output messages even though no errors have occured. For example, stats-snapshot.pl prints "Updating stats history table.", which gets mailed to me every hour. The usual trick of adding "> /dev/null" to the cron entry won't work, because then I won't see errors either: errors are printed to stdout, rather than stderr.

Suggested solution: add a "quiet" option to the scripts, so that they only output errors. Additionally, errors go to stderr, messages to stdout.

Note that several of the scripts already offer a --quiet option, including process-quarantine, expire-quarantine-cache, and load-sa-rules.

Effectively this enhancement ticket applies to send-quarantine-reminders, send-quarantine-digests, and stats-snapshot.
