No issue raised when launched on a non-scaleway host

[remyleone]

When I launch the following command:

$ make IMAGE_DIR=../image-ubuntu/16.04 IMAGE_NAME=pouet IMAGE_VERSION=pouetpouet IMAGE_TITLE=coucou scaleway_image

The process just hangs and I got no information about what is going on.
There are several possible solutions to this:

• At minimum using a timeout on the curl --noproxy * --silent --write-out \n%{http_CODE}\n http://169.254.42.42/conf With a message is the site is unavailable
• Minimal checks about the host running the Makefile
