These are the only defaults currently in OpenMDAO:
DEFAULT_OPT_SETTINGS['IPOPT'] = {
'hessian_approximation': 'limited-memory',
'nlp_scaling_method': 'user-scaling',
'linear_solver': 'mumps'
I see we change nlp_scaling_method here in Aviary, and it is probably intentional, so we should probably just set it.

Those defaults don't seem to kick in at this point (we've only created a fresh pyoptsparse driver at this point, no OM involvement yet), I've verified the dicts start out empty regardless of which optimizer you are using

Summary
AviaryProblem.add_driver() no longer overwrites any settings in driver.opt_settings if they already exist (such as manually set by user beforehand)
