In preparation for the placement REST API getting CRUD operations on resource classes, create ResourceClass and ResourceClassList objects. In this patch, we only add a ResourceClassList.get_all() method that merges the standardized resource classes with any custom resource classes that might have been added to the resource_classes table. Followup patches will add the create(), delete() and save() methods and then finally the REST API changes. Change-Id: Ia9462698fafe3c70a51bb3746a6c2a45175fadf3 blueprint: custom-resource-classes
