Refactor Netatmo integration

[cgtobi]

Breaking Change:

A lot

• for authentication only client id and secret are required, no need to pass your username and password anymore
• public weather sensors are removed and will be added back in a separate PR
• Service set_schedule now requires the name of the home
• webhooks are removed and will be added back in a separate PR
• Services to toggle the light/set it to auto have been removed until implemented in pyatmo

User with existing configuration have to remove/update that and run the config flow dialogue to get their sensors/etc. back using the configuration.yaml option.

Description:

• Implements OAuth2 account linking
• Fixed set_schedule, now requires the name of the home

A couple of lines are missing coverage in the config flow.

Copy and pasting your suggestions wasn't that hard. 😉

I missed a docs PR. Please link it in the description.

That is true, I’ll fix that ASAP.
