Be more verbose about the detected configuration

[penguineer]

This pull request introduces enhancements to logging and error handling in the app.py script and improves the MqttConfig class in mqtt.py for better debugging. The most significant changes include adding logging for missing labels, printing the MQTT configuration and exit status, and implementing a __str__ method for the MqttConfig class.

Logging and error handling improvements in app.py:

• Added a warning message in emit_labels to log cases where a label is missing for a specific chip and feature. (app.py, app.pyL33-R42)
• Added a print statement in main to display the MQTT configuration being used, aiding in debugging. (app.py, app.pyR65)
• Added a print statement in main to indicate when the application is exiting. (app.py, app.pyR91-R96)

Debugging enhancement in mqtt.py:

• Added a __str__ method to the MqttConfig class to provide a human-readable string representation of the configuration, making it easier to debug. (mqtt.py, mqtt.pyR28-R30)
