17325	Add **kwargs to is_valid and several validation methods	jorgeecardona	nobody	"I like to use forms a lot, but sometimes I have to overwrite `__init__` to accept some parameters that change the behaviour of the validation, I was thinking that maybe is better just to add a way to pass some data to the validation methods of the form in order to validate it.

Imagine that I want to create a form to change the email of an user and I don't want to use an argument in the request for ""username"" and use the username from the session framework (I just want to avoid to send the username in the request), I will have to overwrite the `__init__` of the form in order to accept ""user"" as an argument and store it in `self.user` to be used later in `clean_email`. Instead, if we have this new argument in `is_valid` is just to do: `form.is_valid(user=user)`.

This new argument doesn't hurt anyone, and It will help a lot to some of us that use form in this way.
