Public bug reported:

When I create instances which I want to be in the same server group
(--hint group=<UUID>)  with parameter: --num-instances or --min-count
/--max-count   and I have quota_server_group_members set to 5, nova is
spawning all instances regardless quota.

 Example:
nova boot --image $image --flavor small  --hint group=528ff1e3-5a6d-475c-826e-c70d7a56e769 --nic net-id=<UUID> --min-count=2 --max-count=10  test-instance

All Instances has spawned correct. In next request I have an error:
ERROR (Forbidden): Quota exceeded, too many servers in group (HTTP 403) (Request-ID: req-f8aa39cd-2a14-486d-95a9-747ed9eecbfc)


Normally request which should spawn 10 instances (but quota is set to 5) should give an error with Quota exceeded.
The same situation is with  --num-instances parameter.


I check it many times in Juno release and on devstack using nova master branch.


I added simple patch to forbidden creating new instances over quota, but it's should be changed and it's not working correctly with --min-count/--max-count parameter.

** Affects: nova
     Importance: Undecided
