title: context scope at logger level
body: <p>Is there a way to set a context property value in log4net at logger level? We have scopes at thread context and global context and so on. I was wondering if there is a way to set a context variable at the logger instance level?</p>
  
  <p>I know such thing does not exist but to make my point, it would be like</p>
  
  <pre><code> private static ILog _Log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
  
  _Log.LoggerContext.Properties["myVar"] = "someValue";
  //now every log with this logger will use somevalue for the myVar property.
  </code></pre>
  
  <p>Is there a way to do such thing?</p>
