Check the feasibility of using restart to change model parameters in run

[meiertgrootes]

the restart option in combination with model.set_model_parameters() allows model parameters to be changed for an exisiting model (in principle) however. changes are potetially poorly documented. We should revisit this and see what woud be good to formalize the process, possibly alowing for automated execution.

@meiertgrootes I believe this is currently implemented by saving the config yaml file with the current step every time a new run is started. The added description value in the config file may also help in identifying the config parameters for a specific run.

This functionality should be tested in test_model test_model_milestone_multiple.

Could you check whether this sufficiently resolves this issue?
