bugfix: make streaming spans last for the entire duration of the stream

[cbrewster]

Why

The streaming spans were immediately finishing because we were only tracing the construction of the AsyncIterator and not the full iteration.

What changed

• loop and yield each message of the streaming procedures so the span doesn't finish until the async iterator is disposed.

Test plan

• Streaming procedure spans should now last the full duration of the stream procedure
