Terminate simulation if max number of Newton iterations is reached by default

[mrp089]

Problem

We currently continue a simulation without an error or warning when the maximum number of Newton iterations is reached. This might wrongly indicate to the user that a time step has converged.

Solution

By default, terminate the solution with an error if running into the maximum number of Newton iterations. Let the user define a flag to continue but still throw a warning every time this happens.
