This processor is a Data Prepper event record type replacement of `otel_trace_raw_prepper` (no longer supported since Data Prepper 2.0). The processor fills in trace group related fields including the following.
*`traceGroup`: root span name
*`endTime`: end time of the entire trace in ISO 8601
*`durationInNanos`: duration of the entire trace in nanoseconds
*`statusCode`: status code for the entire trace in nanoseconds
in all incoming Data Prepper span records by state caching the root span info per traceId.
