Deprecate using informula wsgi config.

All openstack services uses 99% persent same wsgi apache config.
This patch adds functionality to configure cinder-wsgi.conf from
apache pillar. To do this on cluster level the following file
should be included:
 - system.apache.server.site.cinder

The intree wsgi template will be removed when we switch all model
and cookiecutter to use apache template.
