core: Uploading an image with an existing disk id

While uploading users can choose disk-id for thier uplaod and if
the disk-id was already existing the engine will make a new image
in lock state and fail the prosces. now it will check the disk-id before
creating and will fail if there is another disk-id with the same number.
