Is an initial patch, run all test cases mentioned in the ticket.
I added documentation, where I felt I should be, but I'm not sure.
The only thing not clear to me, as it should behave _state.update_fields.

Fixed #18306 -- Deferred models should automatically issue update_fie…

;) I have renamed the variables!
I will close this pull request for now, until the issues raised in #18306 are resolved.
