The problem is connected with unresolved properties. The old template stored values, which were parsed using resolve_static_data : https://github.com/openstack/heat/blob/master/heat/engine/resources/neutron/loadbalancer.py#L386
So instead resolved monitors id we have only built-in functions. In my vision, we should use self.properties for getting required properties.
