The infra images in the gate have the logrotate package installed on CentOS, but the cron job file has been removed. This patch ensures that the cron job is present in the OpenStack gate. Logrotate is installed by default on CentOS/RHEL 7 systems, so this won't cause issues on non-test systems. Change-Id: I4b4cdbe4f36a957ae3c75b210a9df1f67d5c4127
