Provide proper documentation and type hints for supported config options

Description
===========

The documentation for the Python library refers to librdkafka's [CONFIGURATION.md](https://github.com/confluentinc/librdkafka/blob/master/CONFIGURATION.md) file when it comes to available config options.

However, this is very far from ideal, as it is not immediately obvious, which C types map to which Python types. Furthermore, this prevents autocompletion of configuration properties.

It would be nice if:

1. The full configuration is documented for the Python library as well, listing Python types which are required for each property.
2. The C config is mapped to a Python config TypedDict or Pydantic type, which is then made available through this library. Furthermore, using "." as a separator feels unnatural in Python, where snake case with underscores is preferred.
3. The config used more precise type annotations, which are then internally mapped to the C config. E.g. bootstrap.servers would possibly be a list[str] instead of a str.

How to reproduce
