Adds support for the local shadow service over the local publish/subscribe interface. You can now communicate with the local publish/subscribe message broker on shadow MQTT topics to get, update, and delete shadows on the core device. This feature enables you to connect client devices to the local shadow service by using the MQTT bridge to relay messages on shadow topics between client devices and the local publish/subscribe interface.
This feature requires v2.6.0 or later of the Greengrass nucleus component. To connect client devices to the local shadow service, you must also use v2.2.0 or later of the MQTT bridge component.
