Add simple Request class to Response

I was playing with [ssl: work on anything implementing the socket protocol](https://github.com/adafruit/circuitpython/pull/8954) and testing the quote endpoint on Adafruit (which I know redirects to https) and realized there isn't a way to find that out.

I would like to add a light-weight `Request` class that returns the `method`, `url` and `headers`, like in CPython:

_Here you can see it moved to https_

Use the issue description and its CPython comparison as the starting point. Identify the existing Response implementation and determine how a lightweight Request object should expose method, URL, and headers, then verify that redirect information such as the move from HTTP to HTTPS can be inspected.
