NodeRed container and example flows

[mikehaller]

A pre-defined container manifest for deploying Node-Red (with Node-Red Dashboard UI) and possibly some pre-defined action nodes to interact with MQTT / SDV components.

For hackathons and development reasons, it would be great to have a way to quickly interact with vehicle applications without having to go through a backend. Directly sending MQTT messages, e.g. to the self-update-agent, or directly invoking gRPC endpoints from kuksa-databroker through a Node-Red flow would increase productivity a lot.

Examples:

• Seat Adjuster: Use a Node-Red flow + dashboard buttons to trigger a seat position adjustment (via the seatservice-example)
• HVAC Example: Use a Node-Red flow + dashboard buttons to enable/disable HVAC service
• Ambient Light Service: use Node-Red flow + dashboard buttons to simulate human driver approaches vehicle
• "Local triggering" of OTA Updates: Use a Node-Red flow + dashboard buttons to trigger the deployment of certain use cases (fleet management, hackathon setup, driving score, ...)

@chheis made this manifest already. Based on this I played around with grpc nodes and I don't have success yet.

Is that available somewhere in a public repositor then I can have a look too and try to help.

Would be glad to have this as a contribution to Leda.
