27246	Factor out input template in ClearableFileInput and document template class attributes	Martin Pauly	Martin Pauly	"`ClearableFileInput` uses a template variable in its `render()` implementation (see https://github.com/django/django/blob/master/django/forms/widgets.py#L405) that I would like to factor out as a class attribute. 

This would allow to change the appearance of the 'Select file' button for `ClearableFileInput`, by e.g. wrapping it in a div and adding a span. For normal `FileInput` that is already possible by overwriting the render method, however for `ClearableFileInput` this gets comparably ugly.  
This would be in line with having the other template strings as class attributes.

Also I believe it would be good to document the multiple `template_*` class attributes.
