Avoid copying images for boot
This blueprint aims to add zero-copy support for images. The idea is to take advantage of the following existing features:
1. Nova's image cache
2. Glance image's direct_url
3. Glance image's multiple-location
The work on this patch depends on the support for multiple-locations in order to reduce the hubs an image has to go through before being downloaded and because the multiple locations patch implements an ImageHandler that is intended to handle image operations.
