`@ai_track()` for asynchronous functions

[antonpirker]

Problem Statement

The ai_track decorator currently only works for synchronous functions. If you do something like this:

@ai_track("My async AI pipeline")
async def trigger_ai_async(request):
    with sentry_sdk.start_transaction(
        op="ai-inference", name="The result of the async AI inference"
    ):
        return HttpResponse(b"Hello, world. You're at the metrics trigger.")

You get the following error:

ValueError: The view mysite.urls.trigger_ai_async didn't return an HttpResponse object. It returned an unawaited coroutine instead. You may need to add an 'await' into your view.

Solution Brainstorm

We should update the ai_track to support sync and async functions/coroutines like the trace decorator does:
