Fix the unit test error

1. What is the problem?

           the unit test can not pass.

        2. What is the solution to the problem?

           after the devstac run export the OS_PASSWORD as

           define in the devstack.

        3. What the features to be implemented in the Tricircle to realize the solution?

           I compare the faild and before passed local.conf they are all the same. so

           it is look like a bug of devstack. later on I will pull a bug for this in

           devstack bug list.wait on devstack to fix this bug.
