Bug Description

version: 4.0.1.0-62~newton
Testcase: Random
Let me know if you need a cluster to debug the same.

"ValueError: dictionary update sequence element #0 has length 0; 2 is required" is observed during the sanity run.

Believe we observe this after the fix of https://github.com/Juniper/contrail-controller/commit/061e29144039203fbddb526df962c7dcc936baa2

Invalid return value while capturing auth hdrs

Description: Even on token expiry, registered function
is called to extract headers, and we return None. The middleware
expects empty dict.
But, in neutron plugin for failed authentication we need to raise
401 exception.
To keep UT happy, rbac would return 401 exception when roles are
missing instead of 403, and move out the logic from neutron plugin.
