Install OpenStack services

Many of the OpenStack service states make changes to the databases upon deployment. To ensure proper deployment and to prevent multiple simultaneous attempts to make these changes, deploy a service states on a single node of the environment first. Then, you can deploy the remaining nodes of this environment.

Keystone must be deployed before other services. Following the order of installation is important, because many of the services have dependencies of the others being in place.
