Release 1.0.0: MQTT implementation

[daniel-dona]

Subtasks:

• Move MQTT configuration to a JSON file
• Define subscribing and publishing topics: could be static in code, but also configurable and defined on the JSON file. We can run MSH commands linked to msgs on topics. This could also end up on easy "arbitrary code execution" so to be taken with caution.
• To define how MQTT should communicate with other processes/services to gather information to publish.

Base code is already on the BDK based on Paho MQTT
