Describe the workflow you want to enable

I am trying to use a custom estimator as the base estimator for Adaboost regressor. My custom estimator requires additional fit_params apart from sample weights. As I understand, there is no support for passing other fit_params to base_estimators via AdaBoostRegressor.

Describe your proposed solution

In the fit method of Adaboost, allow **fit_params for base_estimator.

Describe alternatives you've considered, if relevant
