Title:
  Filter AggregateImagePropertiesIsolation doesn't Work

Status in OpenStack Compute (nova):
  New

Bug description:
  Description
  ===========
  I tried to use filter AggregateImagePropertiesIsolation to isolate Windows instance for reducing number of Windows Licenses.

  I think nova scheduler in pike release, filter
  AggregateImagePropertiesIsolation always returned all hosts. If this
  is a bug, filter AggregateImagePropertiesIsolation needs to be fixed.

  
  Steps to reproduce
  ==================
  # add filter to nova.conf and restart nova scheduler
  [filter_scheduler]
  enabled_filters = AggregateImagePropertiesIsolation,RetryFilter,AvailabilityZoneFilter,ComputeFilter,ComputeCapabilitiesFilter,ImagePropertiesFilter,ServerGroupAntiAffinityFilter,ServerGroupAffinityFilter

  # image create with os property
  openstack image create --min-disk 3 --min-ram 512 --disk-format qcow2 --public --file windows.img img_windows
  openstack image create --min-disk 1 --min-ram 64 --disk-format qcow2 --public --file cirros-0.3.5-x86_64-disk.img img_linux
  openstack image set --property os=windows img_windows
  openstack image set --property os=linux img_linux

  # host aggregate create with os property
  openstack aggregate create os_win
  openstack aggregate add host os_win compute01
  openstack aggregate add host os_win compute02
  openstack aggregate set --property os=windows os_win
   
  openstack aggregate create os_linux
  openstack aggregate add host os_linux compute03
  openstack aggregate add host os_linux compute04
  openstack aggregate add host os_linux compute05
  openstack aggregate set --property os=linux os_linux

  # create flavor
  openstack flavor create --ram 1024 --disk 1 --vcpus 1 --public small
  openstack flavor create --ram 4096 --disk 20 --vcpus 2 --public medium

  # create windows instances
  openstack server create --image img_windows --network test-net --flavor medium --max 10 test-win

  
  Expected result
  ===============
  Windows instances can be found in compute01, compute02 only

  Actual result
  =============
  Windows instance was found in every hosts.
