Eclipse MQTT Installation

Installation of the MQTT brokers and storage (queues) is required for establishing communications towards the DeviceNodes.

Additionally, this issue adresses the authorization and authentication for the MQTT. This issue is strongly interconnected towards WP6 (https://gitlab.eclipse.org/eclipse-research-labs/hyper-ai-project/dlt-hyperledger-fabric).

The current AsyncAPI temporarily adresses the Authentication & Authorization via username/password. This must be considered as temporaty and is mentioned for the sake of completeness of the spicification.

Configuration of the MQTT happens via the mosquitto.conf.
