What did you do?
Well, trying to configure Marathon monitoring in Prometheus. Marathon does not support built in authentication, so obviously someone has to use basic_auth to protect Marathon/Mesos. We did the same.

What did you expect to see?
There is already a way to support basic auth for other modules, then why shouldn't we implement that for marathon_sd_config? Copy/Past stuff!! :)
