feat: add App.dependency_overrides #54

Closed adriangb closed 2 years ago

adriangb commented 2 years ago

App.dependency_overrides can be used as a mapping or context manager that yields a mapping

This reduces a lot of boilerplate for users by wrapping their callable in Depends for them and shortening the function calls. It also acts as an ExitStack: users can assign overrides without increasing indentation and they all get unwound when the underlaying context manager exits.

A good example of boilerplate reduction: https://github.com/adriangb/xpresso/pull/54/files#diff-9b5a1fd2a242de1f77eb978967d3f9ff0862f7e6c244fac473a43ceac6f5f808
