Re-open:Drop service-name from ODU connection name

- Fix the bug w.r.t droping service-name from ODU connection
- Service-name is still concatenated to the lower order OTN network
  interfaces and client interfaces.
- Drop the service-name only from the ODU connection, so it will
  not be too long.
- Refer to the patch
