Fixed Python client docstrings (#6780)

* Updated api_client and configuration docstrings

ApiClient: Removed host param, added configuration and cookie param

Configuration: Docstrings are only read from the @property decorated
function, not the setter, moved the more descriptive docstrings from the
setters to property functions

* Ran bin/python-petstore.sh

samples/client/petstore/python/docs/FakeApi.md
