Correct http return code of identify versions api

[zhiyanliu]

Keystone returns 300 http code (Multiple Choices) instead of 200 (OK) [0] when client GETs the api version info that current identify service supported.

This wrong return code causes keystonemiddleware failed at api version query [1] with error "Unable to get version info from keystone: 200", which middleware as a client of keystone lives in a upperlayer service.
