Allow services to use same port with different protocols

kompose fails if compose file declares different protocols for the same port. eg;

...
     ports:
      - 666:666/udp
      - 666:666/tcp
...

This PR adds the port to the output and also makes sure that names are unique for each port/protocol pair.
This is supported with LoadBalancer (kubernetes/kubernetes#2995) so trying to use this config with LB panics.
