* Change the API boundary between stream and camera
Shift more of the stream lifecycle management to the camera. The motivation is to support stream urls that expire
giving the camera the ability to change the stream once it is created.
* Document stream lifecycle and simplify stream/camera interaction
* Reorder create_stream function to reduce diffs
* Increase test coverage for camera_sdm.py
* Fix ffmpeg typo.
* Add a stream identifier for each stream, managed by camera
* Remove stream record service
* Update homeassistant/components/stream/__init__.py

* Remove dependencies on keepalive from StremaOutput and stream_worker
Pull logic from StreamOutput and stream_worker into the Stream
class, unifying keepalive and idle timeout logic. This prepares
for future changes to preserve hls state across stream url changes.
