This test was previously mocking the keystoneauth1 loading code globally which was getting randomly trampled by other tests that were mocking the same thing. This changes the scope on the mock so it should be isolated from other tests mocking out the same thing. Change-Id: Id6c35c583edf0938b5d0178ab2cfb54277f0225f Closes-Bug: #1654393
