    Update device metadata when attaching disks/NICs

    This change ensures that we're updating the instance device metadata
    when attaching or detaching instance volumes or NICs.

    Unlike the other Nova drivers, we're including all Cinder volumes
    in the device metadata, not just the tagged ones. The reason is that
    this allows Hyper-V guests to properly identify attached disk paths.

    Note that the disk mountpoints (e.g. /dev/sdc) are ignored by the
    Hyper-V driver. Also, we cannot override SCSI identifiers, unlike
    the Libvirt driver, which will use volume IDs as SCSI IDs.
