v4 planning

[sondrelg]

• Make ID generator and validator generic, implement transformer (mirror asgi-correlation-id)
• Split celery functionality into a separate package
• Split sentry functionality into a separate package
• Create extras for both
• Update license
• Update test project to handle Django deprecation warnings
• Update to Poetry v1.2
• Update classifiers
• Rework docs (drop sphinx and just have readmes per module?)
• Remove get_guid and set_guid
• Create example projects for each feature

Essentially we want to de-bloat the core a little, making it possible to install the core middleware without anything else. It's possible to install the middleware today, without adding celery as a dependency, but the celery code is still contained in the wheel.

There's also some Sentry + Celery logic to consider @JonasKs. Do we put that in its own third package? Something to think about 🤔

How do you feel about the get_guid, set_guid helpers @JonasKs?

[JonasKs]

Get rid of them imo

asgi-correlation-id doesn't have a UUID_LENGTH package setting. Instead it's a filter option. Should we do that here as well?
