This script is useful if you are trying to find/test some problem with your mesos/marathon/marathon-lb infrastructure.

This script loads all the apps from marathon, finds HAPROXY_\d+_VHOST label and tries to make simple GET request to this endpoint. At the same time, it tries to make direct GET request to host:port of instances of this app. If you set lb option, then it makes GET request via this lb points as vhost name (like curl --resolve vhost:80:lb vhost).
