<!--
Enables shims and translation logic to route volume
operations from the Cinder in-tree plugin to Cinder CSI plugin. Supports
falling back to in-tree Cinder plugin for mount operations to nodes that have
the feature disabled or that do not have Cinder CSI plugin installed and
configured. Does not support falling back for provision operations, for those
the CSI plugin must be installed and configured. Requires CSIMigration
feature flag enabled.
-->
启用封装和转换逻辑，将卷操作从 Cinder 内嵌插件路由到 Cinder CSI 插件。
对于禁用了此特性的节点或者没有安装并配置 Cinder CSI 插件的节点，
支持回退到内嵌 Cinder 插件来执行挂载操作。
不支持回退到内嵌插件来执行制备操作，因为对应的 CSI 插件必须已安装且正确配置。
此特性需要启用 CSIMigration 特性标志。
