thingsboard-gateway MQTT documentation issues

[pbrkr]

The MQTT config documentation for thingsboard-gateway (docs/iot-gateway/config/mqtt.md) does not document the attributeRequests section of the configuration.

Also, the attributeUpdates section is listed as optional but removing this from the config file results in the following error:

ERROR - [mqtt_connector.py] - mqtt_connector - 133 - 'attributeUpdates' section missing from configuration

Hi @pbrkr ,

Thank you for your message, attributeRequests section was left to keep backward compatibility with early versions of the gateway. The notification for missing section was removed in version 2.7 of the gateway.
