#12755: Proposal: Add a method to ModelAdmin to return the form instance

Sometimes we need dynamic fields in a form, depending on the logged in
user or something else. Currently the !ModelAdmin class has a
{{{get_form()}}} method, that returns a form class to be used in admin.
But it would be nice to customize the form instantiation when we are
building dynamic forms.
I've attached a patch that adds a {{{get_form_instance()}}} method to
!ModelAdmin, and it receives the request object. This way we can pass
extra parameters to our dynamic form based on some request attributes. For
example:
{{{
def get_form_instance(self, request, form_class, **kwargs):
return form_classe(user=request.user, **kwargs)
}}}
I don't think it breaks backwards compatibility and it's not a new
feature, so probably could be added to 1.2.
