What does this PR do?
Remove the
WithTraceID128
API that was added to this feature branch (not currently in a dd-trace-go release or in main).Motivation
There isn't enough evidence that we need this API at this time, and the UX is confusing as it is. Currently, the only way to set the trace id programmatically is for root spans using
WithSpanID
, which then applies the trace id. Adding a separate API just to set the higher bits is likely to lead to confusion, and we should redesign this for v2 anyway.Describe how to test/QA your changes
