<!--
Add support for distributed tracing in the kubelet.
When enabled, kubelet CRI interface and authenticated http servers are instrumented to generate
OpenTelemetry trace spans.
See [Traces for Kubernetes System Components](/docs/concepts/cluster-administration/system-traces) for more details.
-->
新增在 kubelet 中对分布式追踪的支持。
启用时，kubelet CRI 接口和经身份验证的 http 服务器被插桩以生成 OpenTelemetry 追踪 span。
