Subject: [PATCH] util: storage: Copy parent's disk metadata to backing chain
 elements

When discovering a disk backing chain the parent disk's metadata need to
be populated into the guest images so that each piece of the backing
chain contains a copy of those. This will allow us to refactor the
security driver so that it will not need to carry around the original
disk definition.
