Ensure logs are rotated appropriately

[martinb3]

Ensure logs are rotated regularly by default, with a monitor to ensure the cluster never fills up. Once we're doing a lot of logging with the above items, this will be critical. Related to #6.

Seems like the best-practice would be to require the ditro-specific logrotate package to be installed as a dependency of this stack, and include the one-off file(s) in /etc/logrotate.d/ to properly handle log rotation as needed. I don't think logrotate requires a full recipebook for this, it's a simple package commonly available and has a pre-defined 'add more items' directory on various distro's.
