Arseny Boykov 0f948618ba Add model signature generation (#1034)
* Add right __init__ signature generation

* Add params overlay support for custom __init__, enhance tests

* Change fake_ini creation to solve AttributeError in cython
AttributeError: attribute '__code__' of 'cython_function_or_method' objects is not writable
Possible there's other attrs that cannot be set in cython, but can't check myself yet

* Cython compatibility, add __signature__, ignore non-identifiers fields
Moved tests to separate file
Moved __init__ creation to utils

* Remove # pragma: no cover

Co-Authored-By: Samuel Colvin <samcolvin@gmail.com>

* Fixed adding signature to doc, some compatibility fixes

* Changed None to tuple() for py3.8 compatibility

* Finally (hope so) fix issues with closure. Add new docstring each time

* coverage for UndefinedType

* Checking signature more simple and obvious way

* Changed doc caption to simple message, used Undefined, merge conflicts

* Compatibility with py3.6

* Add changes/ file

* Ah, that space... Reformatted and ready to go!

* Update pydantic/main.py
