Removed the **kwargs parameters from calcparams_cec, calcparams_desoto, and sapm. Python automatically returns a TypeError upon user input of unexpected parameters.

Do we want to remove these kwargs without deprecation? I am not opposed since I don't think it would hit many people and it would most likely be in code that can be fixed relatively easily.

Depending on the decision about deprecation, the note in the whats new needs to move to breaking changes or to deprecations.

I'm ok without deprecation, I doubt that kwargs was used much for these PVSystem methods. Agree with @wholmgren about the placement of the whatsnew note.

Thanks @wholmgren and @cwhanse for the feedback. I moved the whatsnew note to the breaking changes section.

Thanks @wholmgren and @kanderso-nrel for the feedback! I updated the whatsnew file per your suggestions.
