VehicleRoutingProblem cannot load TSPLib(CVRP)

Description
The VehicleRoutingProblem cannot load the CVRPData from the TSPLIB.
Because the Problem only implements InstanceConsumer of VRPData, but the TSPLIB exports CVRPData, it cannot be loaded.
A patch is attached which adds an InstanceConsumer of CVRPData to the VRP.
Since a CVRPData is as VRPData, a contravariant mechanism of instance consuming would be nice, but I am not sure if this is doable in an easy way.

r11285 The ProblemInstanceProvider is now contravariant. Therefore the ProblemInstanceManager discovers all derivations of InstanceProvider<IVRPData>.
Note that there was a problem with covariant InstanceConsumers with the ProblemInstanceProviderView in the past (#1981). Due to the fixes from #2110 this problem should not occur anymore.
