For a very long time we've been parsing and using the lxc images as provided by upstream lxc. While these images are functional there are by no means optimal. In general they're quite a bit larger than they need to be and contian a lot of little sharp edges that have cut us over the years. This change removes all of the lxc image cache parsing and meta-data linking and simply downloads the rootfs a given url. To maintain compatibility with the legacy images a script has been created to parse the image index and return the legacy image url. The result of this change: * Access to smaller more optimal base image which is well known by the corresponding communities. * Deployers now have the ability to set and forget the download url for an internal image instead of having to create a cache infrastructure compatible with the lxc download template. * Any rootfs tarball will work as an image. * Fewer tasks are executed and less memory is consumed resulting in faster deployment times. * The base cache has a uniform meta-data setup giving all container types the same access to config, devices, and templating.
