Class to serve Nova Metadata API with apache mod_wsgi in place of nova-metadata-api and service.
Serving Nova Metadata API from apache is the recommended way to go for production because of limited performance for concurrent accesses when running eventlet.
When using this class you should disable your nova-metadata-api service.
