Add an openwebbeans.properties property to not scan jars with an extension

org.apache.webbeans.scanExtensionJars = true 

Can be added to openwebbeans.properties to disable the scanning of the jars with an extension. Long story short, this is the official CDI behavior since 1.1 but in 1.0 it was the opposite so we kept it in most of our default implementations to ensure backward compatibility.

org.apache.webbeans.scanExclusionPaths = ....,/my-extension-jar 

was a workaround until today to get the specification behavior.

Side note: in general you don't need to set this and default will work smoothless until the extension scanning duplicates the beans it register programmatically.
