Using an empty config, the debug output of "az" calls shows this:
| cli.azure.cli.__main__: Command ran in 0.598 seconds (init: 0.103, invoke: 0.495)
| telemetry.main: Begin splitting cli events and extra events, total events: 1
| telemetry.client: Accumulated 0 events. Flush the clients.
| telemetry.main: Finish splitting cli events and extra events, cli events: 1
| telemetry.save: Save telemetry record of length 3823 in cache
| telemetry.main: Begin creating telemetry upload process.
| telemetry.process: Creating upload process: "/usr/bin/python3 /usr/lib/python3/dist-packages/azure/cli/telemetry/__init__.py /home/bastian/.azure"
| telemetry.process: Return from creating process
| telemetry.main: Finish creating telemetry upload process.
As telemetry is not fundamental for the functioning of the program, it
needs to get user approval first.
