Jamie Lennox f8c150a9cc Create a Config object
The _conf_get ugliness in auth_token middleware has been around for a
long time now to handle the abstraction from different oslo.config
options and the paste overrides. This logic is now also being needed in
other middlewares. Extract this into a common config object that has a
better interface and is easier to work with.
