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

ptracetest doesn't support ignoring trace IDs.

Describe the solution you'd like

Have a way to reset trace IDs to empty traces.

Describe alternatives you've considered

We use this code to reset trace IDs:

func ignoreTraceID(traces ptrace.Traces) {
	for i := 0; i < traces.ResourceSpans().Len(); i++ {
		rs := traces.ResourceSpans().At(i)
		for j := 0; j < rs.ScopeSpans().Len(); j++ {
			ss := rs.ScopeSpans().At(j)
			for k := 0; k < ss.Spans().Len(); k++ {
				span := ss.Spans().At(k)
				span.SetTraceID(pcommon.NewTraceIDEmpty())
			}
		}
	}
}
