Public bug reported:

After https://blueprints.launchpad.net/nova/+spec/instance-group-api-
extension, nova has the feature of creating instance groups with
affinity or anti-affinity policy and creating vm instance with affinity
/anti-affinity  group.

If did not enable ServerGroupAffinityFilter and
ServerGroupAntiAffinityFilter, then the instance group will not able to
leverage affinity/anti-affinity.

Take the following case:
1) Create a group with affinity
2) Create two vms with this group
3) The result is that those two vms was not created on the same host.
