To be able to support multi-level repository names, the API has been adjusted to disabiguate routes tagged image manifest routes and tag list routes. With this effort, the regular expressions have been defined in a single place to reduce repitition and ensure that validation is consistent across the registry. The router was also refactored to remove the use of subrouters, simplifying the route definition code. This also reduces the number of regular expression match checks during the routing process.
