* Update nest to use stream thumbnail when it exists
* Update nest camera to always pull still image from stream
Update nest camera to always pull the still iamge from the stream component,
removing the use of the separate ffmpeg call, and removing use of the nest event
image. Image for events can now be pulled using the media source APIs, rather
than relying on the camera snapshot.
* Simplify a comment
* Remove more unused variables
* Simplify comments, image, and test code
* Remove assertions for placeholder images
* Add an entity service for saving nest event related snapshots
Add an entity service `nest.snapshot_event` for recording camera event
related media to disk. This is based on `camera.snapshot` but takes in
a parameter for a Nest API event_id.
PR #58299 adds `nest_event_id` to events published by nest so that they can
be hooked up to this service for capturing events.
Future related work includes:
- Height & Width parameters for the rendered image
- Support video clips for new battery cameras
- An API for proxying media related to events, separate from the camera image thumbnail
- A Nest MediaSource for browsing media related to events
* Revert debugging information
* Add test coverage for OSError failure case
* Add service description for nest snapshot service
* Reduce unnecessary diffs.
* Sort nest camera imports
* Remove unnecessary if block in snapshot
