Description of change

NOTE: This PR adds breaking changes.

This PR aims to add static typings to the redis.client.Redis class. This is still a work in progress and this PR must not be merged yet. Please give me any feedback on that.

In some parameters, I don't know what is the proper type. I'll fix these later.

Hi @bitterteriyaki, thanks for your desire to contribute!

Currently redis-py supports Python 3.8 up to and including 3.11, and support for 3.12 is planned.

In general it's best to use language constructs that work in all these versions. For example Union[str, None] instead of str | None, which is available only since 3.10. The Self construct can be made available in versions earlier than 3.11?

Hi, @gerzse. Thank you for the answer. Since Python 3.7 was dropped, It would be nice to update the documentation.

Alright. I'll be changing this.

According to the typing documentation, no. I'll also be changing this.

Instead of typing.Self, I am using from __future__ import annotations which is available for old Python versions and is a library for "future" which is not available for these versions.
