fix the same udp port and tcp port, update nginx.conf error

[chenpengdev]

becase there is no check protocol, when service use same port, nginx.conf only exist tcp port information。

...
  ports:
  - name: "80"
    port: 80
    protocol: TCP
    targetPort: 80
  - name: 80udp
    port: 80
    protocol: UDP
    targetPort: 80
...
