+Migrate ServiceAccount volumes to use a projected volume

+`serviceaccount_stale_tokens_total` to monitor workloads that are depending on the extended
+tokens. If there are no such workloads, turn off extended tokens by starting `kube-apiserver` with
+flag `--service-account-extend-token-expiration=false`.

+将 ServiceAccount 卷迁移到使用由
+ServiceAccountTokenVolumeProjection 组成的投射卷。集群管理员可以使用
+`serviceaccount_stale_tokens_total` 指标来监控依赖于扩展令牌的工作负载。
+如果没有这样的工作负载，你可以在启动 `kube-apiserver` 时添加
+`--service-account-extend-token-expiration=false` 标志来关闭扩展令牌。
