Modernize Python Client packaging (#104)

Accompanying apache/airflow#36763 where we
fix and modernize the way how Python client gets generated, this
on is result of applying the modernisation:

* converting project configuration to pyproject.toml and removing
  all setup.* and requirements files
* converting to modern packaging backend (hatchling) to build
  wheel and sdist packages (with reproducibility)
* using hatch test environment definition and coverage to run tests
* we deleted release instructions and dev tools (the ones in Airflow
  will be used to generate and sign the package)
* similarly .pre-comit-config.yml is not needed as the client
  gets generated in the Apache Airflow project.

All those are going to be maintained in Apache Airflow project
as part of apache/airflow#36763 as a single
source of truth - when new Python client gets released the project
files will be overwritten from those prepare from Airflow project,
this is just initial PR to seed the new
