Promote ipopt_solver_wrapper to a general utility

[blnicho]

In #706 an Ipopt solver wrapper was introduced that reads the Ipopt output and returns a number of useful convergence statistics including the number of iterations, solve time, checking for regularization at the solution, etc.. I think this is a super useful utility that should be moved out of contrib/parmest to somewhere like pyomo/util or pyomo/solvers.

See the wrapper here: https://github.com/Pyomo/pyomo/blob/main/pyomo/contrib/parmest/utils/ipopt_solver_wrapper.py

I agree. This should really be moved to the actual ipopt solver instead of a wrapper function.

It would be best if this functionality was inside ipopt. Second-best would be if the wrapper was implemented as a Pyomo solver.
