Fix proposed to branch: master
Review: https://review.openstack.org/135273

[Wu Hong Guang (whg)]

I think this is a critical bug for integration test .

This bug causes all integration tests failure because the log out is called during the test case clean up,

[Julie Pichon (jpichon)]

I agree this is critical in the context of the integration tests, and we want to fix this ASAP in order to be able to run the tests on the gate. However in the greater context of the project, it is not as critical - no functionality is critically broken, it's not blocking patches from merging, etc.
