Description of problem:
While installing OpenShift on OpenStack with Kuryr reusing a node network, additional parameters are required using the provision.yml playbook.

I had to add the following parameters in order to get the provision playbook to succeed:
openshift_openstack_router_id
openshift_openstack_node_network_id
openshift_openstack_node_subnet_id

According to the documentation I would only have to define the following parameters:
openshift_openstack_router_name
openshift_openstack_node_subnet_name

The *_id parameters should be determined by the provision playbook with the _name parameters mentioned above.

Version-Release number of the following components:
(overcloud) [cloud-user@bastion openshift-ansible]$ git describe
openshift-ansible-3.11.9-1
(overcloud) [cloud-user@bastion openshift-ansible]$ git branch

How reproducible:
Always with this environment, all.yml and OSEv3.yml

Steps to Reproduce:
clone release-3.11 openshift-ansible, setup all.yml and OSEv3.yml attempt to run playbooks:

. /home/cloud-user/overcloudrc
ansible-playbook -vvv --user openshift -i inventory -i openshift-ansible/playbooks/openstack/inventory.py openshift-ansible/playbooks/openstack/openshift-cluster/prerequisites.yml 2>&1 >> /home/cloud-user/scale-ci/logs/openshift_prerequisites.log
ansible-playbook -vvv --user openshift -i inventory -i openshift-ansible/playbooks/openstack/inventory.py openshift-ansible/playbooks/openstack/openshift-cluster/provision.yml 2>&1 >> /home/cloud-user/scale-ci/logs/openstack_provision.log

^ provision.yml playbook fails with attached log

Actual results:
Please include the entire output from the last TASK line through the end of output if an error is generated

Expected results:

Additional info:
