SpanBuilder and Baggage

[mladedav]

I have a SpanBuilder, a parent context with baggage and then I tried calling

let span = builder.start_with_context(&tracer, &parent_cx);

However, the new span did not have the same baggage as the parent context. From what I could see, the context is just parsed for parent ID, trace flags, sampling and such.

Is that by design? I though this was a way to create a child span which as I understand it should have almost the same context (except for the active span).
