Allow download raw VHDs to XenServer

Registered by John Garbutt on 2014-01-24

When users upload VHDs to glance, its nice not to only support OVA wrapped VHDs.

This blueprint looks to ensure:
* we check glance says its OVF or OVA before attempting to extract the image
* if there is no container_format or it is BARE, then we try to download the VHD directly

For the implementation, we will use wget and md5sum to avoid any overheads around streaming the full image through python code, now there is no need to worry about stream untaring and uncompressing the image.
