What changes were proposed in this pull request?
HDDS-2022 introduced new freon tests, but the initial root span of opentracing is not created before the test execution. We need to enable opentracing to get better view about the executions of the new freon test.

How this patch can be tested?
Start an ozoneperf cluster:
If HDDS-2296 is not yet merged, stop old-style freon:
Start new freon test:
Open the jaeger web ui: http://localhost:16686/
Choose freon under the service and click to the search.
On the right side you should see results with the name freon: OzoneClientKeyGenerator and with multiple sub-spans.
Without the patch you can see entries with strange name (...span without root...)
