Title:
  Legacy GroupAffinity and GroupAntiAffinity filters are broken

Status in OpenStack Compute (Nova):
  In Progress
Status in OpenStack Compute (nova) juno series:
  Fix Committed

Bug description:
  Both GroupAffinity and GroupAntiAffinity filters are broken. The
  scheduler does not respect the filters and schedules the servers
  against the policy.

  Reproduction steps:
  0) Spin up a single node devstack 
  1) Add GroupAntiAffinityFilter to  scheduler_default_filters in nova.conf and restart the nova services
  2) Boot multiple server with the following command 
  nova boot --image cirros-0.3.2-x86_64-uec --flavor 42 --hint group=foo server-1

  Expected behaviour:
  The second and any further boot should fail with NoValidHostFound exception as anti-affinity policy cannot be fulfilled.

  Actual behaviour:
  Any number of servers are booted to the same compute node
