Comment 4 for bug 1504128

Verified on MOS 8.0 RC#1

STV(only negative case):

1. Deploy cluster with controller and compute nodes
2. Go to controller node
3. Add /etc/hiera/override/openstack-region.yaml with content:
region: region_eu
nova:
  region: region_eu
glance:
  region: region_eu

4. Add "override/openstack-region" in /etc/hiera.yaml
5. execute
# ruby /etc/puppet/modules/osnailyfacter/modular/astute/upload_cirros.rb

Actual and expected result: we should get message "internalURL endpoint for image service in region_eu region not found"
