rhel-osp-director: failed to update 7.0->7.2 :ControllerNodesPostDeployment: resources.ControllerOvercloudServicesDeployment_Step7: Error: resources[1]: Deployment to server failed: deploy_status_code : Deployment exited with non-zero status code: 6

Environment:
openstack-tripleo-heat-templates-0.8.6-94.el7ost.noarch
instack-undercloud-2.1.2-36.el7ost.noarch

Steps to reproduce:

1. Deploy 7.0 with "openstack overcloud deploy --templates --control-scale 3 --compute-scale 1  --neutron-network-type vxlan --neutron-tunnel-types vxlan  --ntp-server 10.5.26.10 --timeout 90 -e network-environment.yaml"

2. Update the undercloud node and reboot it - verify nothing reports as failed.

3. Follow the procedure to prepare the overcloud nodes for the update and update the included environment files.

4. Run the update command: "yes "" | openstack overcloud update stack overcloud -i --templates   -e /usr/share/openstack-tripleo-heat-templates/overcloud-resource-registry-puppet.yaml    -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml    -e /usr/share/openstack-tripleo-heat-templates/environments/net-single-nic-with-vlans.yaml    -e /usr/share/openstack-tripleo-heat-templates/environments/updates/update-from-keystone-admin-internal-api.yaml  -e network-environment.yaml


Result:
The update fails:
