Slack Notify - Add Username / Icon variables / customization

Would be great if we could send ‘username’ and ‘icon’ variables to change the user / icon that’s posting. Currently it only uses the ‘defaults’ as setup in configuration.yaml. Would be similar to how it currently uses ‘target’ to override ‘default_channel’.

Would love to see username and icon added - seems it would be easy - just not for a not python coder such as myself… :frowning:
