* explicitly specify the dirs that are getting rotated
* app log rules are now moved to logrotate.ejs
* we keep task logs for a week
Some testing notes:
* touch -d "10 days ago" foo
* logrotate /etc/logrotate.conf -v to test rotation. there is a state
file created in /var/lib/logrotate/status. If we have a 'daily' rule,
it will get processed only after a log line in status exists and it's atleast
1 day old timestamp.

readable
