- Add API to configure a node port range
- Map each port to same port on sub-cluster
- Implement haproxy settings for workload services, including tcp connect
health checks
TODO (later):
- The existing singular NodePort field is now ignored for this service,
since the node port range is used instead, and so should be removed,
which will require some refactoring of base service types.
