Trains a POI geofence

Trains the POI geofence geofenceId using a device telemetry. The POI geofence boundary is defined using radio measurements. The geofence is trained using a telemetry that the device with trackingId has ingested during the specified time range, while being at this point of interest. Only telemetries that have been ingested during the last 24 hours can be used in the training.

Optionally, a WLAN scan be used for the training.
