Log4Net StackdriverAppender: Use %property values in custom labels

Is your feature request related to a problem? Please describe. Attempting to use %property syntax on custom label values. It shows up in Stackdriver like this:

labels: {
  Key:  "%property{AccountID}"   
...
 }

I want the value inserted at runtime, similar to what I can do with the message:

<conversionPattern value="%property{AccountID} …

Describe the solution you’d like I’d like to label my logs with some context from the application.

<customLabel>
      <key value="AccountID" />
      <value value="%property{AccountID}" />
</customLabel>

Describe alternatives you’ve considered Put the dynamic data into the log message directly.

Additional context

• I think this is where a replacement would happen.
• I saw that adding new labels dynamically was prevented completely in #1036. I would just be looking to change the values dynamically.

@bryanroth It’s already in beta on nuget: https://www.nuget.org/packages/Google.Cloud.Logging.Log4Net/2.4.0-beta01

Any news on this? It would be required for us to put the %property{log4net:HostName} in one label to filter our logs.
