Attempt to retrieve the vmdk descriptor data-pair

Browse Source 
VMDK formats such as monolithicFlat and vmfs require two files to be
fully consumable by the Nova drivers (a descriptor-data pair: *.vmdk and
*-flat.vmdk).
On the upload of the descriptor (*.vmdk), upload_image.sh should attempt to
retrieve the *-flat.vmdk. The same way, the descriptor should be
retrieved when a flat disk is uploaded.
On success, the upload script will be able to use the flat disk as the image
content and the relevant descriptor settings as the image metadata.
