Subject: Make cron's logrotate schedule configurable

Kolla-ansible allows user to change logrotate.conf,
problem is that logrotate cron file is running
daily by default in all distros, this is sometimes
not enough. So, this patch is adding script and
way how to reconfigure schedule of logrotate job
(cron file).

Needed-By: https://review.opendev.org/c/openstack/kolla-ansible/+/813039
