[WIP] Add functionality to have user-specific convergence criteria for nonlinear solvers

[tarun-mitruka]

See #182

TO-DOs

• Change the solver-dependent structs, for example, NRConvergenceCriteria to criteria-dependent structs. This should then be overloaded with bool operator()(...){} for different solvers. Remove the MAKE_ENUM and then pass the criteria-dependent structs directly to the nonlinear solvers. This would allow easy extensibility for the users.
• Fix the bug in Python tests
• Implement convergence criteria for trust region method
• Update CHANGELOG
• Fix in ikarus-examples, if needed
• Use DUNE::AlwaysFalse as per the comments (see convergencecriteria.hh)

Decisions to be made

• May be a solverState is needed to have nice constructors. See also refactor observer patterns and unify logging information #260
