[asafchen-dig]

The task is about adding an additional data to the ScalingInsight. In order to see this insight:

1. Clone https://github.com/digma-ai/otel-sample-application-dotnet repo
2. Run Sample.MoneyTransfer.API project
3. Run ClientTester project
4. Hover the method SampleInsightsController.Lock

The new section in the insight json:

"rootCauseSpans": [
      {
        "sampleTraceId": "794DBD49DC6678ACFF80A1EDBDC41BF5",
        "name": "WaitForLock",
        "displayName": "WaitForLock",
        "instrumentationLibrary": "SampleInsightsController",
        "serviceName": null,
        "codeObjectId": null,
        "kind": "Internal"
      }
]

Note that the RootCauseSpan contains all the fields of SpanInfo, which is used to find the span in the code
