Drop in replacement for sklearn.model_selection.permutation_test_score

It'd be great to have a dask wrapper for permutation_test_score so that permutations of gridsearches are easier to run in dask.

Start by reading sklearn.model_selection.permutation_test_score and determine the drop-in behavior the Dask wrapper must preserve. Done means permutations of grid searches can be run through Dask with compatible inputs and results; the issue does not name project files or tests, so locating the appropriate integration points is part of the work.
