Description of the problem/new feature
While it's relatively "easy" to check for convergence by looking at params['tol_history'][-1] < tol for most algorithms, there are a few like brpls and goldindec that have several different exit criteria and make parsing tol_history really difficult. It'd be nice to just add a success item to the output params like SciPy does with its optimizers to allow easily checking for convergence.
