Azure IoT Hub parses the user agent information using the property
name DeviceClientType, so the client must send it with that name
otherwise the user agent string is not properly stored on Azure.
A change in the property name to "dct" can only be done after the hub is
also updated to support that name/alias.
The crash was caused because the handle to the MQTT client was being
incorrectly passed to esp_mqtt_client_stop (indirection bug).
Also removed setting the ESP MQTT buffer size, letting it use its
default value.
These are the stacktraces of the crashes that this change fixes:
