Comment 1 for bug 1781439

I did some search and found that
https://review.openstack.org/#/c/565604/31/releasenotes/notes/consumer_generation-f576ac2594b24e2e.yaml
says only impact POST and PUT

while
https://github.com/openstack/nova/blob/master/nova/api/openstack/placement/handler.py#L99

only support GET ,so any update should be included? The consumer_generation id ?
