* http: Add headers key to json[_message] * Add google_assistant component This component provides API endpoints for the Actions on Google Smart Home API to interact with Google Assistant. * google_assistant: Re-add fan support * google_assistant: Fix Scene handling - The way I originally wrote the MAPPING_COMPONENT and the way it's actual used changed so the comment was updated to match that. - Use const's in more places - Handle the ActivateScene command correctly * google_assistant: Fix flakey compare test Was failing on 3.4.2 and 3.5, this is more correct anyway. * google_assistant: Use volume attr for media_player
