The PR #6532 completes the upgrade of jaeger-v1 write pipeline to v2 storage API. However, there is no unit tests that would track the whole pipeline from receiving a network message to passing it to a mock v2 storage implementation. We would like to add it.

There is a comment in the code complaining about the lack of such test:

However, we could use HTTP endpoint of OTLP receiver to submit OTLP trace data as JSON.

The main validation is to ensure that a v2 mock trace writer is passed to the SpanProcessor and that writer is invoked with the expected trace submitted via HTTP.

The test should also validate that the tenancy information is propagated all the way from the client to the storage (as part of the Context in the WriteTraces call.

This issue is a good preparation for the mentorship project #6458.
