Rationale: when deploying the proxy, operators should be the only ones that have access to the administrative functionality - primarily, the management of partitions. This split makes it possible to deploy the forwarding portion of the proxy independently of the administrative portion. The appropriate changes in tests, setup.cfg, and configuration files (see: I7cf25e47ecff47934b50c21000b31308e1a4c8a9) were made. Certain helpers that are reused for wsgi transport implementations were extracted to a common location to aid reuse. Unit tests were also simplified for the proxy, with the intent to make them more thorough in coming patches. New test requirement: httpretty - used to perform request mocking during proxy transport unit tests Change-Id: Ia26981a78c477a896370c48768e71f45c364c769 Implements: blueprint placement-service
