Metrics to Topic Fanout

[skobow]

This feature enables re-publishing metrics of Sparkplug Data messages to dedicated topics.

When receiving a data message on spBv1.0/DairyPlant/NDATA/Refrigeration each metric will be republished on a corresponding topic:

{
        "timestamp": 1486144502122,
        "metrics": [{
            "name": "Inputs/Temperature",
            "timestamp": 1486144502122,
            "dataType": "Float",
            "value": 29.2
}, {
            "name": "Inputs/Humidity",
            "timestamp": 1486144502122,
            "dataType": "Float",
            "value": 55.9
}],
    "seq": 0
}

The first metric will be published on spBv1.0/DairyPlant/NDATA/Refrigeration/Inputs/Temperature:

{
            "name": "Inputs/Temperature",
            "timestamp": 1486144502122,
            "dataType": "Float",
            "value": 29.2
}

The second metric will be published on: spBv1.0/DairyPlant/NDATA/Refrigeration/Inputs/Humidity

{
            "name": "Inputs/Humidity",
            "timestamp": 1486144502122,
            "dataType": "Float",
            "value": 55.9
}
