Expose an entry point to list auth_token middleware config options
Register a 'keystonemiddleware.auth_token' entry point in the
oslo.config.opts namespace which, when called, returns a list of the
configuration options which may be registered by the project at runtime.
The idea here is that the sample config file generator can query this
and include the returned options in the sample config file of any
applications which use the middleware, e.g. currently the options
were listed in 'keystone_authtoken' section for those major projects.
