Having a method that raises NotImplementedError is usually not ideal, since the implementations of the class can't delegate control through super to the parent or to other classes found in the MRO. Instead, we mark a priori ReportingHandler as a base class, leaving the implementation of `publish_event` empty. Change-Id: Id5c442b6998743b1caffbad627847ee5e88f2982
