Title:
  remove run_filter_once_per_request from GroupAntiAffinityFilter

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  Now GroupAntiAffinityFilter was defined to run once per request, but
  this is not right, as filter_properties['group_hosts'] will be updated
  after one host was selected for one VM. So if there are multiple VMs
  in one request, the VM deployment will not obey
  GroupAntiAffinityFilter, as some VMs might be deployed on to same host
  with current VMs.
