 The HorizontalPodAutoscaler API also supports a container metric source where the HPA can track the
 resource usage of individual containers across a set of Pods, in order to scale the target resource.
 This lets you configure scaling thresholds for the containers that matter most in a particular Pod.

 HorizontalPodAutoscaler API 也支持容器指标源，这时 HPA 可以跟踪记录一组 Pod
 中各个容器的资源用量，进而触发扩缩目标对象的操作。
 容器资源指标的支持使得你可以为特定 Pod 中最重要的容器配置规模扩缩阈值。
