New EDP re:dy component (#16426)

* add new EDP re:dy platform

* lint

* move api code to pypi module; fix lint

* fix lint; remove unused import

* pass aiohttp client session and hass loop to platform

* update requirements_all.txt

* fix docstring lint

* normalize quotes

* use async setup_platform

* improve entities update mechanism

* doc lint

* send update topic only after loading platforms

* lint whitespaces

* mute used-before-assignment pylint false error
