Trace IDs for Tracegen

[huy7070]

Hi. How do I get the trace IDs of the generated traces, so I can view them in Grafana?

I only see this output when I run the tool:

./tracegen -otlp-endpoint localhost:4318 -otlp-insecure -otlp-http -traces 20
2022-03-10T15:11:48.142-0600	INFO	tracegen/main.go:75	starting HTTP exporter
2022-03-10T15:11:48.157-0600	INFO	tracegen/config.go:94	generation of traces isn't being throttled
2022-03-10T15:11:48.157-0600	INFO	tracegen/worker.go:89	traces generated	{"worker": 0, "traces": 20}
2022-03-10T15:11:48.168-0600	INFO	tracegen/main.go:87	stopping the exporter

That would be a great improvement. Would you like to contribute such a change?
