    Commits e147e00 and c4f1bff in Ganeti add support for userspace-only
    disks. That means that we could have an instance without a local
    block device (e.g. using the embedded support in QEMU for rbd by
    passing -drive file=rbd:pool/image_name without the need of a
    /dev/rdbX device).
    
    This patch does the following:
    
    Introduce a find_disk() helper method that first checks the
    DISK_IDX_PATH and if it is not exported then it returns
    DISK_IDX_URI.
    
    Introduce a losetup_disk() helper method that is used during
    export/import and in case we have an ntfsdump/extdump image type.
