Test out new stream component with TVs

https://www.home-assistant.io/components/camera/

from Dev tools -
{
"entity_id": "camera.living_room_camera"
}
```yaml
action:
service: camera.play_stream
data:
entity_id: camera.yourcamera
media_player: media_player.chromecast
```

Start with the camera component link and the Dev Tools service payload shown in the issue. Test whether camera.play_stream can send camera.living_room_camera, or camera.yourcamera, to media_player.chromecast and confirm that the stream displays on the TV; the issue does not name any files or tests.
