Title: [openstack|image] Check for glance version (fog only supports v1)

Check if version returned by service catalog is supported, as Fog only suports glance version v1 (or v1.1). I'm working on v2 support.

Same behaviour as [openstack compute](https://github.com/fog/fog/blob/master/lib/fog/openstack/compute.rb#L406)
