Subject: [PATCH] Allow Consul api to set default config for addr

As can be seen in https://github.com/hashicorp/consul/blob/91ee7990ccf27ab7fccff746f8df0df65c3c583d/api/api.go#L390 the API also defaults to localhost:8500, however it can also use the environment variable CONSUL_HTTP_ADDR which is useful when fabio is run with nomad.

This change makes sure that the existing default stays working, but it now works better by default in more situations
