commit 2f2b0e954d7738c2bf49a48a708cc0ce2b19e726
Author: Mike Fedosin <mfedosin@xxxxxxxxxxxx>

    Don't set empty kernel_id and ramdisk_id to glance image
    
    In some cases, if 'allow_additional_properties' option is
    disabled in Glance, 'kernel_id' and 'ramdisk_id' are considered
    the usual properties and cannot have None values. So it's better
    always omit these props and never send them to Glance if they are
    empty.
