The 'Upgrade os-net-config' task relies on os_net_config_need_upgrade.stdout to evaluate the when condition but the os_net_config_need_upgrade only gets registered at step 3 https://github.com/openstack/tripleo-heat-templates/blob/master/puppet/services/tripleo-packages.yaml#L55-L58 so the 'Upgrade os-net-config' task fails at any other step different than 3 as the os_net_config_need_upgrade var is undefined.
