fix: neutron designate integration (#1389)

Set _neutron_external_dns_driver before __neutron_helm_values and __neutron_ovn_helm_values. In other case it is always omitted.

Even if we set external_dns_driver to designate: https://opendev.org/openstack/openstack-helm/src/branch/master/neutron/templates/configmap-etc.yaml#L222
There is a bug/typo  upstream which sets Keystone URI to Designate endpoint: https://opendev.org/openstack/openstack-helm/src/branch/master/neutron/templates/configmap-etc.yaml#L239

Adding auth_url and url accordingly until this will be fixed.
