Preserve actual production playbook in examples

Since Sahara is moved to inactive state, we can not provide further
releases of the role either, which means that Sahara should be dropped
from the integrated repo.

With that it's worth to preserve actuall playbook that was used for
deployment as example playbook, in case somebody needs to use old
role/service version in their deployments.
