Title: ENH: allow predict to pass through patsy for transforms

@njsmith Does this seem reasonable for predict? If there's a formula present and you give exog, it passes through dmatrix. This won't work for models that define their own predict in the results class without a super call, but none for which formulas are available do that.

I thought to also introduce a transform=True keyword, but I want to do some kind of template for the results predict docs first.
