If the clientmanager is unable to create a keystone session (due to insufficient auth parameters or something else) then the exception caused by this shouldn't be ignored, as was the case. On the other hand, we don't want this behaviour in the case of the 'complete' command, so this is now properly detected. Change-Id: If4f453d23cc87900cda752e9ffbcf41ded59e26f Closes-Bug: #1444640
