would be nice to add a small test case so we detect breakage with ASGI context extraction. |

Happy to provide a test, but didn't find an easy way to do it, without adding a propagator as dependency, or mocking attach/extract and validating what is received there. If you have a better test scenario in mind, I can definitely implement it and add it to this PR. |

@owais, I was able to add a test by taking advantage of how the default propagator works, so we check the provided |

propagator as test dep sounds fine. I think all instrumentations that propagate context should do this if they don't already. |

For ASGI requests, we must use `request.scope` instead of `request.META`. This is because `ASGIGetter` retrieves the `headers` key from the carrier [0], which is only present in `request.scope`.
