* Change datetime.now() to dt_util.now() in cases where the functionality should stay the same
These changes should not affect the functionality, rather cleanup our codebase.
In general we would like integrations to not to use datetime.now() unless there's a very good
reason for it, rather use our own dt_util.now() which makes the code aware of our current time
zone.
* Use datetime.utcnow() for season sensor to get offset-naive utc time
