glance_image provider should support usage of a proxy

[Luca Lesinigo]

As far as I can understand it is not possible to let glance_image use a proxy when downloading images from http / https, this makes it impossible to use it in a network without direct access to the web server holding an image.

It would be really useful to have parameters that allow specifying a proxy and pass them to Net::HTTP.
