Introduces a mechanism for switching between API versions, and implements it in a proof-of-concept fashion for the Keystone v3 API. Converts the existing Users and Projects API methods to use it. This changed some method signatures, and therefore altered a number of views and tests. However, all code related to the version cahnges is contained in the api.keystone module. This seems like a sane process going forwards. Future TODOs are marked in the code, including auto-detection of API versions and better endpoint URL construction. Partially implements blueprint api-capability-detection Change-Id: Ied04200fe6c257aac2241d36628965a3bb6658b9
