Introduce CM Weather Manager and Weather Provider Services API.
The CM Weather Manager can be used by apps to request weather
updates.
The Weather Provider Services API allows a third party developer to
implement a weather service to process weather update requests and
update the CM Weather Content Provider data which can be consumed by
any other app holding the required permission.
