Redis connection doesn't support password configure in zaqar, so redis-server can not set a password. If redis service doesn't set a password, it will suffer a large number of attacks. The patch will support password configure in zaqar. In addition, it is needed to add unit test in the previous patch[https://review.openstack.org/#/c/511676/].
