Deploy Apache as web front-end for gluster-swift

Swift can alternatively be configured to work as a request processor of
Apache server. This alternative deployment scenario uses mod_wsgi of
Apache to forward requests to the swift wsgi application and middleware.

'client' <---> 'Apache2+mod_wsgi' <---> 'middleware' <---> 'core swift'
