示例1: ServiceAndDeploymentGroups
// ServiceAndDeploymentGroups breaks the provided graph of API relationships into ServiceGroup objects,
// ordered consistently. Groups are organized so that overlapping Services and DeploymentConfigs are
// part of the same group, Deployment Configs are each in their own group, and then BuildConfigs are
// part of the last service group.
