Bug Description

To ensure that Keystone upgradability is not broken it may be useful to add a new testing job. We can test how different Keystone versions work together. We will create multi-node OpenStack installation (controller + keystone node) of master-1 version and then upgrade one of keystone services to master. After that, we can run tests.
