Steps to reproduce:
1. Build the modules modules/matterhorn-usertracking-service-api and impl.
2. The build artifacts are matterhorn-usertracking-api and impl, without the "service" in their names
3. This is confusing to developers as well as system administrators in need of managing installations
The directory of these two modules should probably be changed to remove the "service" part, so they comply with the naming of other modules.
