Subject: configure site_webapp::haproxy to ship a haproxy config::fragment to
 setup the haproxy listener 'bigcouch-in'. This haproxy listener is configured
 to listen on port 4096 (arbitrarily chosen) and balance across the locally
 configured stunnels to the bigcouch instances

It may be that we will need some additional haproxy options for handling
persistence, cookies, or other HTTP headers, I'm unsure as of this moment
