Runner stops the first time we have a non-convergence for a given configuration

Even if a configuration doesn't converge at a given timestep, we would still want to run it on subsequent timestep. For now grid2op runner stops as soon as there is a non-convergence

I think we need to discuss with Benjamin in order to know how to do this. From what I've seen, it's not really easy to do this atm.
