Code Issues Proposed changes

Added Keystone and RequestID headers to CORS middleware 

CORS middleware's latent configuration feature, new in 3.0.0,
allows adding headers that apply to all valid origins.
This patch adds headers commonly used in openstack to neutron's paste
pipeline, so that operators do not have to be aware of additional
configuration magic to ensure that browsers can talk to the API.
