Comment 4 for bug 1752808

The roles_data was not updated when I got the error, so the following file was used https://raw.githubusercontent.com/openstack/tripleo-heat-templates/master/roles_data.yaml

Deleting the deprecated_nic_config_name on the roles_data file ended up with the following error:

Processing environment files /home/stack/tripleo-heat-templates/environments/net-single-nic-with-vlans.yaml
