the marathon api for applications and setup the appropriate frontend (listening on port 80)
with backends for each application.
HAProxy will look for a hostname prefixed with the application name and route to that backend.
Using this technique you can wildcard a dns host to all your masters
(say, *.example.com) and an application you launch (say, "myapp") will be
available at myapp.example.com. This can be disabled by setting the haproxy_script_location
to an emptry string "". It will only be installed if HAProxy is present.
