The response of Sierra's OpenStack is improved.

It is good news that the response of Nova Client is improved on Sierra's OpenStack.

This issue doesn't show up on Essex version, so India's OpenStack is fine. But Grizzly version has lots on Keystone's database, and it had been making the authentication process slow. We took a serious look and tuned MySQL configuration.

Here's the result of the improvement.
