Log rotation

Hi,
It would be great to have logrotate preconfigured, since /var/lib/ghost/content/logs folder is ever-growing. That cause issues when deploying to k8s, since pod would eventually crash:

Start at the repository's image packaging entry point and trace how /var/lib/ghost/content/logs is created and written. Check the Kubernetes deployment context and the reported ENOSPC failure to determine where rotation belongs. Done means the image has a documented, testable way to prevent unbounded log growth without filling the pod's storage.
