[Python] Create simple HTTP server example using Flask

[ianmcook]

Describe the enhancement requested

The HTTP server example at arrow-experiments/http/get_simple/python/server uses Python's built in http.server which lacks many important features and is not recommended for production use. We should create another simple Python HTTP server example using Flask.

@paleolimbot has an example here showing how to do it: https://github.com/paleolimbot/2023-11-21_arrow-over-http-scratchpad/blob/main/app.py
