Instrumentation config add traceid to http server response header

Is your feature request related to a problem? Please describe.

The scenario is to expect that the response header can be added quickly in the service close to the frontend without extending HttpServerResponseCustomizer

Does this requirement involve sepcs?

Describe the solution you'd like

The configuration is probably like this，default value is null

otel.instrumentation.common.http.server.tracei.header.name=X-Test-TraceId

Similar behavior to below

@AutoService(HttpServerResponseCustomizer.class)
public class TestAgentHttpResponseCustomizer implements HttpServerResponseCustomizer {

  @Override
  public <T> void customize(
      Context serverContext, T response, HttpServerResponseMutator<T> responseMutator) {

    SpanContext spanContext = Span.fromContext(serverContext).getSpanContext();
    String traceId = spanContext.getTraceId();

    responseMutator.appendHeader(response, "X-Test-TraceId", traceId);
  }
}

Describe alternatives you've considered

No response

Additional context

No response

Start by tracing the existing HttpServerResponseCustomizer entry point and how instrumentation configuration keys are defined and consumed. Check whether the proposed otel.instrumentation.common.http.server.tracei.header.name setting can apply across HTTP server instrumentations, then verify the configured header and trace ID behavior with the relevant HTTP response tests.
