Description
At the moment users can pass in a durations matrix for costs and we will minimize *the total number of vehicle driving hours*. In contrast, this ticket is about *minimizing the total duration vehicles are on the road*.
---
Implementation:
Minimize the route's end cumul var. for the time dimension. This will minimize the overall completion time.
```c++
for (auto vehicle = 0; vehicle < model.vehicles(); ++vehicle)
model.AddVariableMinimizedByFinalizer(model.CumulVar(model.End(vehicle), timeDimension));
```

Research direction
No file or test is named. Locate the Node.js binding path for routing cost and duration handling, then compare it with the proposed C++ time-dimension finalizer logic; done means the binding can minimize total vehicle time on the road rather than only total driving hours.
