HostPath转localDir、emptyDir或flexVolume

• 单个HostPath替换为localDir配置方式：

  "coordinator.cci.io/hostpath-replacement": '[{"name":"source-hostpath-volume","policyType":"replaceByLocalDir","localDir":{"sizeLimit":"1Gi"}}]'

• 单个HostPath替换为flexVolume配置方式：

   "coordinator.cci.io/hostpath-replacement": '[{"name":"source-hostpath-volume","policyType":"replaceByFlexVolume","flexVolume":{"driver": "huawei.com/fuxidisk", "fsType": "ext4", "options": {"volumeType": "sata", "volumeSize": "10Gi"}}}]'

  EVS目前支持普通、高I/O、超高I/O三种规格，volumeType根据实际情况填写：

  表1 EVS规格

  EVS规格	类型	适用场景
  普通I/O	sata	后端存储由SATA存储介质提供，适用于大容量，读写速率要求不高，事务性处理较少的应用场景，如：开发测试、企业办公应用。
  高I/O	sas	后端存储由SAS存储介质提供，适用于性能相对较高，读写速率要求高，有实时数据存储需求应用场景，如：创建文件系统、分布式文件共享。
  超高I/O	ssd	后端存储SSD存储介质提供，适用于高性能、高读写速率要求、数据密集型应用场景，如：NoSQL、关系型数据库、数据仓库（如Oracle RAC、SAP HANA)。

• 全部hostPath都忽略：

   "coordinator.cci.io/hostpath-replacement": '[{"name":"*","policyType":"remove"}]'

• 多个hostPath差异化替换策略：

  "coordinator.cci.io/hostpath-replacement": '[{"name":"source-hostpath-volume-1","policyType":"remove"},{"name":"source-hostpath-volume-2","policyType":"replaceByLocalDir","localDir":{"sizeLimit":"1Gi"}},{"name":"source-hostpath-volume-3","policyType":"replaceByEmptyDir","emptyDir":{"sizeLimit":"10Gi"}}]'
