title: How to remove properties from log entries in ASP.Net Core
body: <p>I'm using Serilog with ASP.Net Core 2.0, writing to RollingFile using JsonFormatter.<br/> Followed the instructions here to configure: <a href="https://github.com/serilog/serilog-aspnetcore" rel="nofollow noreferrer">https://github.com/serilog/serilog-aspnetcore</a>.  <br/> Everything works great, but in every log entry I get the following properties that I did not log:</p>
  <ul>
  <li>SourceContext</li>
  <li>RequestId</li>
  <li>RequestPath</li>
  </ul>
  <p>I presume they are being added by the ASP.Net Core logging framework. How can I get rid of them?</p>
