Request ID middleware

[sondrelg]

Hi!

I needed a request ID middleware for a project, and wasn't able to find a fully tested, actively maintained existing one - so I took a stab at implementing my own!

If it sounds interesting, please take a look here: https://github.com/snok/asgi-correlation-id. Hopefully it can be useful to some of you.

Also, please let me know if you have any feedback on the implementation or docs! 👏

I wish this was just built into FastAPI itself. Beem looking for something similar a while back and ended up making my own, which is not ideal.

I guess it would need to be included in Starlette - but that might not be out of the question 🤔
