Title: Avoid confusing cloudstack user data servers

Cloudstack does not cope well with trailing slashes. If other userdata servers can handle a lack of trailing slash, this would be useful and unbreak amongst others cloud-init for Ubuntu 13.10 at least.

I don't have means to test if EC2 handles trailing slashes well, maybe you guys can ?
