Disable AdaptiveSampling when using UseApplicationInsights

[Tadimsky]

There is no way to set EnableAdaptiveSampling to false when using the WebHostBuilder extensions.

public static IWebHostBuilder UseApplicationInsights(this IWebHostBuilder webHostBuilder)
{
    webHostBuilder.ConfigureServices(collection =>
    {
        collection.AddApplicationInsightsTelemetry();                
    });

    return webHostBuilder;
}

Should this be possible? Right now I'm having to ditch this extension and do it myself:

webHostBuilder.ConfigureServices(collection =>
{
    collection.AddApplicationInsightsTelemetry((options) =>
    {
        options.InstrumentationKey = appInsightsKey;
        options.EnableAdaptiveSampling = false;
    });
});
