check_estimator outside of unittests

Thanks @remiadon ! +1 for a function to list all estimators, basically adapting https://github.com/scikit-learn/scikit-learn/blob/1986c89a12203a2df02f65e0764acea2bcd027cc/sklearn/utils/__init__.py#L1146

However, tests should use pytest and parametrize_with_checks decorator.

@remiadon Would you be interested in making a PR with it?

@rth thanks for pointing out the get_all_estimators method.
And yes I will make a PR for this :)
