Ops file for image registration through wakame-init

[Metallion]

Problem

Currently it is a bit difficult to register now images in Wakame-vdc because the following information is needed.

• md5 checksum
• image size archived
• image size extracted
• Label/UUID of the root partition

Solution

• Create a YAML file containing this information that is distributed along with the image.
• Add a feature to vdc-manage to read this file and register and image through it.

The file should contain a download URL for the image. If only the file is provided, vdc-manage should download and register it. If the file is provided along with an image, the provided image should be registered using the info in the file.

Currently vdc-manage needs you create a backup object and an image separately. It should get one new command that creates both in one fell swoop.
