pinging @liqiangz as code owner

@TylerHelmuth
Besides, am I miss something ? I think @JaredTan95 maybe the code owner marked in https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/.github/CODEOWNERS#L183 :)

You are correct, I accidentally pinged the exporter's owner.

I see all existing tests are passing, but do any tests need updated because of the new mappings? Is there a tests that exists that should now also be testing that TraceId, ParentTraceSegmentId, and ParentSpanId are mapped correctly?

No... there are no tests needed updated in this pr. The existing TestSwReferencesToSpanLinks test covers the modification, it just added data passing through attributes and make no changes to the existing rules. Also the TraceId/ParentTraceSegmentId/ParentSpanId may mapped between different spans, I think there may not be a persuasive test in "pre-build data mapping".

As a replacement, I do an integration testing and I get the result which it's my expectation

I get export data with otlphttpexporter

then I find the parent span which has SegmentId and SpanId related to the child in Jaeger:

Adding ready-to-merge since the code owner has also approved.
