Fix failure of unit test TestCinderAllCmd

After introducing the commit 93d26e40098c966e7d791a9fb6152244a9f9409d
unit test TestCinderAllCmd fails if a test environment has
/etc/cinder/cinder.conf with proper backend configuration.
We should mock out some variables not to depend on test environment.
