Provide a pattern for auth plugins to load themselves from a config object. The first user of this will be auth_token middleware however it is not likely to be the only user. By doing this in an exportable way we are defining a single config file format for specifying how to load a plugin for all services. We also provide a standard way of retrieving a plugins options for loading via other mechanisms. Blueprint: standard-client-params Change-Id: I353b26a1ffc04a20666e76f5bd2f1e6d7c19a22d
