When max_placement_results is less than the total number of nodes in a deployment it may not be possible to use the affinity, anti-affinity, same host or different host filters as there is no guarantee for placement to return the expected hosts under such situations. This patch disables the max_placement_results parameter when nova queries placement for ``GET /allocation_candidates`` if the request_spec.scheduler_hints containts any of group, same_host or different_host keys. NOTE(mriedem): The RequestGroup used in this backport has to use nova.api.openstack.placement.lib.RequestGroup because nova.objects.RequestGroup didn't exist until Stein with change I46c97d2641d9685ef59771314665a17a5236097d.

If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems.
