[GRAILS-10623] Fixed issue, controllerClass and controllerNamespace now available in filters

Fixed based on a previous PR. This fixes the issues detecting during builds. It provides functionality for filtering scoped to a namespace using a namespaceRegex filter and namespaceExcludes. It also fixes a few areas where fetching class by logicalPropertyName was no longer correct due to the controller potentially having the same name in a different namespace. (Uses the request attribute GRAILS_CONTROLLER_CLAS instead).
