MQTT Support

[ClementAbadie]

Hello,

First of all, a big Thank you for this amazing work ! :)
3 Neato saved here ;)

The web interface is really nice but the support of MQTT could allow to make this project compatible with virtually any home automation system since MQTT is a very common protocol.

Futhermore, it's really easy to add it to the project since ESPhome support it natively.
The only things to add are :

• In the YAML :

mqtt:
  broker: !secret mqtt_ip
  port: !secret mqtt_port
  username: !secret mqtt_username
  password: !secret mqtt_password
  topic_prefix: esphomeneato
  discovery: false
  discovery_prefix: esphome
  log_topic: esphomelog

• In the web interface : A way to input the secrets like you did for wifi credentials.
• In the doc : The names of the commands (button, switch, sensor etc.). For example :
  • Start cleaning :
    • TOPIC : button/house_clean/command
    • MESSAGE : PRESS
  • Send to base :
    • TOPIC : button/send_to_base/command
    • MESSAGE : PRESS
  • Led ON :
    • TOPIC : switch/led/command
    • MESSAGE : ON
  • Led OFF :
    • TOPIC : switch/led/command
    • MESSAGE : OFF
  • UI State :
    • TOPIC : sensor/ui_state/state

Easy to say, harder to do. I know... but it could be a great improvement for the projet :)

Best regards,
Clément.

I like the idea, the new config system makes this very easy to implement, I will try to add this soon, will look into how hard it is to add and see what I can do, for my probably after ros, but maybe before? Of course open to any PR
