[42/50] [abbrv] git commit: refs/heads/qemu-img - Initial skeleting for qemu-img wrapper

[wi...@apache.org]

Initial skeleting for qemu-img wrapper

This should eventually be used by the KVM agent at every place where it
calls qemu-img.

It should also sync with the KVM Agent so that we don't have multiple places
where we define Disk Formats.
