ldn: Implement calls of UserLocalCommunicationService (#829)

* ldn: Implement calls of UserLocalCommunicationService

- Implement `IUserServiceCreator: CreateUserLocalCommunicationService` according to RE.
- Implement `IUserLocalCommunicationService` calls:
  - Every calls in this interface are layered to `NetworkInterface`.
  - `GetState` according to RE.
  - `InitializeOld`, `Initialize` and `Finalize` stubbed with the appropriate result code and some TODO according to RE.
  - `AttachStateChangeEvent` according to RE.

* Fix var name and TODO comments

* Fix review
