	/**
	* A Docker Hub notification.
	*
	* As we always sort them to the 'docker' group, and the registry only fires
	* one kind of event, this is pretty straightforward without any need for
	* configuration files or analyser class.
	*
	* HOW TO IMPLEMENT PAYLOADS SORT PER REPOSITORY?
	*
	* If you want to extend this to sort Docker images through some rules, we
	* suggest you add a feature request to Docker to include source repository
	* for the image, then call the GitHubPayloadAnalyzer with this repo instead
	* of implementing a new one. This will allows to avoid to maintain two sets
	* of configuration, one for the GitHub repos, one for the Docker repos.
	*
	* Even without that, you can probably be safe with a class or a method to map
	* GitHub and Docker names, either because they are the same, either because
	* there is a prefix: e.g. nasqueron/arcanist and nasqueron/docker-arcanist.
