In reset, also add possibility to change the parameters, forecast parameters, max iter and skip time steps

[BDonnot]

• parameters
• forecast parameters
• max iter
• skip initial time steps

See how the "init state" has been added there and do the same by calling change_parameters, change_forecasts_parameters, self.chronics_handler.set_max_iter etc.

I will not do parameters and forecast parameters as it does not really make sense for a single episode. If modified it should be modified for all the next episodes
