This adds the CORS support middleware to Aodh, allowing a deployer to optionally configure rules under which a javascript client may break the single-origin policy and access the API directly. In previous patches, proper paste support for gabbi was added. This patch modifies the paste.ini file for both aodh and gabbi, adds the CORS configuration fixture to support unit tests, and adds CORS into configgen.
