POTEL 31 - Use span id of remote parent

[adinauer]

📜 Description

Set parentSpanId when continuing a trace from an incoming request or other remote span.

💡 Motivation and Context

Traces were broken because on an incoming request, OtelSentrySpanProcessor did not set the parentSpanId on the span correctly. Traces were not referencing the actual parent span but some other (random) span ID which the server doesn't know.

💚 How did you test it?
