Pull request overview

Adds helper utilities to define/apply more granular (per-spoke) solver configuration, including per-iteration mipgap settings, and wires these into several spokes.

Changes:

• Refactors solver spec config creation into add_solver_specs() and new add_mipgap_specs() helpers.
• Introduces apply_solver_specs() to apply per-spoke solver name/options/mipgap overrides when building spoke dictionaries.
• Updates multiple spokes to use the shared helpers instead of inline mipgap wiring.

File	Description
mpisppy/utils/config.py	Adds reusable config helpers for solver + mipgap specs and applies them across spokes.
mpisppy/utils/cfg_vanilla.py	Adds apply_solver_specs() and simplifies _hasit (currently with a behavior-changing bug).

mpisppy/utils/solver_spec.py:73

• If no solver name is found and name_required=False, this function will fall through and return solver_name/solver_options without them ever being initialized, leading to an UnboundLocalError. Initialize them before the loop (e.g., to None/{}) and return those defaults when no match is found.

            solver_options = sputils.option_string_to_dict(ostr)
            break
    else:
        if name_required:
            # Leaving in underscores even though it might confuse command line users

Thanks, although I'm having trouble resolving some issues in the confidence interval code. If I don't get back to this, it would be a good topic for a future call.
