kubernetes（k8s） 安装 Prometheus + Grafana
组件说明
MetricServer：是kubernetes集群资源使用情况的聚合器，收集数据给kubernetes集群内使用，如 kubectl,hpa,scheduler等。
PrometheusOperator：是一个系统监测和警报工具箱，用来存储监控数据。
NodeExporter：用于各node的关键度量指标状态数据。
KubeStateMetrics：收集kubernetes集群内资源对象数 据，制定告警规则。
Prometheus：采用pull方式收集apiserver，scheduler，controller-manager，kubelet组件数 据，通过http协议传输。
Grafana：是可视化数据统计和监控平台。
