Improve logrotate handling

Currently, if a new log is added that is not using runit, we have to manually add the log to our logrotate configuration, !5319 (merged) for example. It would be great if we could capture this better, and maybe find a way to make this enabled by default?

At a minimum, I think we should

1. Audit bundled services and make sure non-runit logs are being rotated when they should be. I think in almost all cases, they should be.
2. Make the developers documentation explicitly clear that this needs to be added.
