API : JSON not enough generic / stream name change

[MaelREBOUX]

Hello

JSON structure provide by the API is not unique : it changes for each flow / parametre because the name of the monitored flow is a "node" in the JSON structure. This name is actually duplicated in the infos above for the stream : "sensor_name".

It would be better to have : /streams/sensor/measurements/ then /streams/[AirBeam-F | AirBeam-PM | AirBeam-RH]/measurements/
