    Write readme.txt into old log directories

    This should help operators find the new log files. We do have them
    documented, but not everybody reads every word in the docs :)

    The readme creation has ignore_errors: true so that if the directory
    isn't present at all (e.g. on deployed server environments, which
    don't have openstack packages installed), we don't fail the deployment
    when we're not able to create the readme.
