[feature request] Support resume (and potentially other tune.run args)

[Yard1]

From: https://discuss.ray.io/t/tunesearchcv-resume/2414

Is there a way to resume TuneSearchCV like with tune.run? I am using named log folders, but it seems like the resume parameter is missing–Is it possible to add? or would you recommend I try to find a workaround, like using the vanilla tune.run?

I think we could just have a tune_run_kwargs argument somewhere, probably in fit that would allow the user to pass any parameter they want to tune.run, including resume.
