Properly parse IIB Responses in OTEL

This commit detects a typical IIB API response, which consists of a
tuple with a Flask.Response object and the HTTP code.

Example:

```
def add_bundles() -> Tuple[flask.Response, int]:
    ...
    return flask.jsonify(request.to_json()), 200
```

With this we no longer see the following messages in IIB-API logs:

```
Invalid type Response in attribute 'result' value sequence.
Expected one of ['bool', 'str', 'bytes', 'int', 'float'] or None
```
