Adaptive sampling enabled by default with the server telemetry channel

[SergeyKanzhelev]

With the upcoming beta release of Application Insights SDK for web applications adaptive sampling will be enabled by default. Read more about adaptive sampling: microsoft/ApplicationInsights-dotnet#80

Disable it by removing the following from ApplicationInsights.config:

<TelemetryProcessors>  
  <Add Type="Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel.AdaptiveSamplingTelemetryProcessor, Microsoft.AI.ServerTelemetryChannel">  
    <MaxTelemetryItemsPerSecond>5</MaxTelemetryItemsPerSecond>  
  </Add>  
</TelemetryProcessors>

How do we disable this for AspNetCore for 2.0? There is no config file.

Does anyone knows why the AdaptiveSamplingTelemetryProcessor processor is added twice in the config once with Event and once with Event ?
