Add logrotate class to Apache

Adding this subclass to httpd configuration, to allow
modules using this manifest to setup log rotation for
apache on demand.
Please note that apache is installing a logrotate file by
default here, but naming that on same way will overwrite it,
and allow our desired log rotation.
