* instrumentation/asyncio: catch CancelledError exception in tests After a29242f49386c097defce500b138dc00f06ce300 we are re-raising the CancelledError so we need to catch it on the caller side. Fix #2688 * instrument/asyncio: don't test anext on python < 3.10 Since it's not available there. * instrumentation/asyncio: use unittest.skipIf instead of reimplementing it --------- Co-authored-by: Leighton Chen <lechen@microsoft.com>
