Requires a short DB migration

Bug 814647

No downtime required.

1. clean up old state - remove sp-admin01:~socorro/persistent/crontabbers.json and clear crontabber_state table ("update crontabber_state set state = '{}';")
2. copy /etc/socorro/{crontabber.ini, common_database.ini, common_logging.ini} from stage admin box to prod admin box and customize common_database.ini
3. ensure that automatic email is disabled/in test mode
4. test that crontabber works manually - as socorro, run "/data/socorro/application/scripts/crons/crontabber.sh"
5. modify prod crontab to be http://rhelmer.pastebin.mozilla.org/2164745
6. enable nagios monitoring - "PYTHONPATH=/data/socorro/application:/data/socorro/thirdparty/ /data/socorro/application/socorro/cron/crontabber.py --admin.conf=/etc/socorro/crontabber.ini --nagios"
