FieldArray should have a beforeSubmit prop

Are you submitting a bug report or a feature request?

Feature Request

What is the current behavior?

Field Arrays don't make use of "beforeSubmit" as regular Fields do.
Perhaps it was left out intentionally, but I would expect Field Arrays to accept most, if not all, of the same props as a regular Field.

What is the expected behavior?

Field Arrays would employ "beforeSubmit"

Other information

I may try and resolve this myself one day but as stated above, I just don't know if there was a very good reason for leaving this out in the first place.
