This PR changes the vehicle-consumption service, the co2-calculator service and the rest-api service to handle vehicle URIs.
Also includes a change to the co2-calculator to always ask the depot service if it is a top level vehicle (like "/bus" or "/tram") and a line is provided.
co2 calculator will also gracefully handle if the depot service does not know the line.
