Robbe Sneyders 073f0d446e Update examples for Connexion 3.0 (#1615)
This PR updates the examples for Connexion 3.0 and merges them for
OpenAPI and Swagger.

2 examples required some changes to make them work:
- The reverse proxy example required some fixes to the
SwaggerUIMiddleware to leverage the `root_path` correctly. This is
included in the PR.
- The enforced defaults example requires the json validator to adapt the
body and pass it on. We currently pass on the original body after
validation, and I'm not sure if we should change this. I'll submit a
separate PR to discuss this.

========================
Custom Validator Example
========================
.. warning::
This example is outdated. Currently validation no longer adapts the body.
TODO: decide if validation should adapt body or how we want to enable defaults otherwise.
In this example we fill-in non-provided properties with their defaults.
Validator code is based on example from `python-jsonschema docs`_.
Running:
.. code-block:: bash
$ python app.py
Now open your browser and go to http://localhost:8080/v1/ui/ to see the Swagger
UI. If you send a ``POST`` request with empty body ``{}``, you should receive
echo with defaults filled-in.
