Add extra Power On options

[bigdogevan]

The problem I have is my TV does not reliably turn on with WOL or Smartthings. I have tried many different approaches and each one takes a substantial amount of time real world testing (and comes with a lot of flack from my wife every time it doesn't work) and the solution I ended up with is an ESP8266 behind my TV with an IR blaster connected. I then use a script to power on the tv which sends the IR command. It works great, but sometimes there is a slight delay (up to 5 seconds) because I also have to use a smart plug with energy monitoring to update the TV state as I find the state updates are not always accurate.

It would be good to include an "external" power on solution, other than WOL or Smartthings. In my case I'd like the IR command script to execute as the power on option (or something similar).

The major reason why I want this feature is voice commands through Google (potentially affects other voice assistants). I have my media_player.living_room_tv exposed to google, but I'm almost certain that when I give the voice command "turn on the living room tv" that it calls media_player.turn_on or whichever action samsungtv smart uses, which will in turn be either the WOL or smartthings command (which does not work every time consistently for me). This is also why I can't use the power button on my mushroom media player card.
