IAsyncEnumerable support in Azure Functions V3

Hi!

In order to return data in a stream and being more memory friendly it would be fantastic if the AF could support IAsyncEnumerable return. Example:

[FunctionName("Function1")]
public static async IAsyncEnumerable Run(
[HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
ILogger log)
{
log.LogInformation("C# HTTP trigger function processed a request.");
for (var i = 0; i < 10; i++)
{
yield return i;
}
}

Thanks
