This reverts commit 2603a774b112dc6e25f9e7b2071124ea3d3d0012, which converted cinder to use cluster configuration for stateless services. While well-intentioned, this causes problems due to the lack of a proper migration for those backends which are not able to support ACTIVE-ACTIVE configuration. Configurations that do not support ACTIVE_ACTIVE driver will have the volume service fail to start, which will cause a service outage.
