Migrate existing tests to new NetworkConfigurationUpdaterImpl.

- Migrate old unit tests of NetworkConfigurationUpdaterImplCros to new NetworkConfigurationUpdaterImpl.

I combined this migration with the following steps to simplify the process:
- Replace username hash in NetworkConfigurationUpdater by User* (was suggested earlier already and simplifies the unit test)
- Add a pure interface to ManagedNetworkConfigurationHandler and a Mock implementation.
- Remove unused NetworkConfigurationUpdaterImplCros
