<!--
When disabled, legacy behavior in service load balancers and
node disruption will ignore the `node-role.kubernetes.io/master` label in favor of the
feature-specific labels provided by `NodeDisruptionExclusion` and `ServiceNodeExclusion`.
-->
禁用此门控时，服务负载均衡器中和节点干扰中的原先行为会忽略
`node-role.kubernetes.io/master` 标签，将使用 `NodeDisruptionExclusion` 和
`ServiceNodeExclusion` 对应特性所提供的标签。
