POST /sensors/data and GET/sensors/data should contain the sensor ID in the URL, like all other endpoints do.

We require the user to put it in the JSON body (even in a to-be-deprecated entity address).

We should move to POST /sensors/(id)/data and GET/sensors/(id)/data.

Technical challenge: Linking the sensor ID to the JSON data, as SensorDataDescriptionSchema (and its derivatives) need the sensor Id to do some validations on the input (e.g. sensor.event_resolution).

We should then announce the deprecation, while both sets will remain working for one more version.
