Adds authentication support for Quantum. Generates a context object and stuffs it into the 'quantum.context' variable in the WSGI environment. This will be used in conjunction with authZ, later. Partially implements blueprint authorization-support-for-quantum. Change-Id: I8af171c2f11a08db5ee41e609d60ad203548650d
