Auto-discoverable class that registers LoggingFeature based on configuration properties. 
 Feature is registered if any of the common properties (see LoggingFeature) is set or any of the client properties is set and context's RuntimeType is RuntimeType.CLIENT or any of the server properties is set and context's RuntimeType is RuntimeType.SERVER. 

The registration does not occur if the feature is already registered or auto-discoverable mechanism is disabled.
