Actions: Allow camera turn off/on

[shred86]

Checklist

• I checked for similar existing requests (both open and closed) before posting.
• My request is generic, other users may benefit from it too.

Proposal

Add the ability to create an action for camera's to use the camera.turn_off and camera.turn_off service.

Additional info

This is obviously possible through normal Home Assistant automations but I like trying to keep as much of my alarm related actions/automations within Alarmo.
