Add device information to MQTT message payload

[stas-demydiuk]

Add basic device information to each MQTT message to make it possible to somehow recognize devices (type, manufactor, model, etc.) for 3rd party plugins

@Koenkk Any chances to have this merged? These changes are required to make working my integration with Domoticz (https://github.com/stas-demydiuk/domoticz-zigbee2mqtt-plugin)

Thanks for the pr!

As this functionality is not always needed and because it adds a lot of stuff to the payloads, could you make this a setting in configuration.yaml? For homeassistant we have homeassistant: true, I propose to make something similar for domoticz (domoticz: true)

@Koenkk what do you think about more generic option in configuration.yml file, smth like

mqtt > send_device_information: true|false

as this option might be useful for some other integrations as well not especially for Domoticz?

[Koenkk]

I'm fine with that, what do you think of include_device_information?

@Koenkk Sounds good, updated the PR

Great, thanks!
