Deploying with OVS fails - puppet-user: Error: Function lookup() did not find a value for the name 'ovn_dbs_vip'

[Harald Jensås]

Deployment with '/home/centos/tripleo-heat-templates/environments/services/neutron-ovs.yaml' to deploy OVS instead of OVN fails, puppet is doing a lookup for 'ovn_dbs_vip'

I think I may have found the issue.

The ironic environment enabled ovn:
https://opendev.org/openstack/tripleo-heat-templates/src/branch/master/environments/services/ironic-overcloud.yaml#L2

BTW: Ironic and OVN absolutely does'nt play since OVN now raises an error[1] when Ironic tries to set the extra_dhcp_opts.
