Expose Daydream in HomeAssistant

[tango2590]

I use my tablet as a digital picture frame when it's not in use. I use Fotoo to display pictures from my Google Photos albums which works great. I tell Fully Kiosk to use Android Daydream as the screensaver, then select the Fotoo app in the Daydream settings. Sending the Start Daydream command in the Fully Kiosk admin page works, but it's not yet available in the HA integration. Can this be added?
