Add memory set eviction config to kcc

What type of PR is this?

What this PR does / why we need it:

Which issue(s) this PR fixes:

Special notes for your reviewer:

English

  • Adds optional EnableCPUBurst and EnableCPUBurstForMainContainerOnly fields to CPUBurstConfig.
  • Adds optional MemorySetEvictionConfig to EvictionConfig.
  • Updates CRD definitions and generated deepcopy code for the new API fields and types.
  • Existing configurations remain compatible because all new fields are optional.
  • Downstream consumers should support the new fields when they construct, validate, serialize, or default these API types.
  • Consumers can use the CPU burst fields to control global CPU bursting and restrict it to the main container.
  • Consumers can use MemorySetEvictionConfig to control memory-set eviction.
  • The change includes generated-code updates. It does not include documentation or test changes.

简体中文

  • CPUBurstConfig 添加可选字段 EnableCPUBurstEnableCPUBurstForMainContainerOnly
  • EvictionConfig 添加可选的 MemorySetEvictionConfig
  • 更新 CRD definitions 和生成的 deepcopy 代码,以支持新增 API 字段和类型。
  • 由于所有新增字段均为可选字段,现有配置保持兼容。
  • 下游消费者在构造、校验、序列化或设置这些 API 类型默认值时,应支持新增字段。
  • 消费者可以使用 CPU burst 字段控制全局 CPU bursting,并将其限制到 main container。
  • 消费者可以使用 MemorySetEvictionConfig 控制 memory-set eviction。
  • 本次变更包含生成代码更新,不包含文档或测试变更。

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 4a4ef

The configuration API can still accept THP default values outside its documented supported set, potentially allowing invalid node configuration to be stored and applied. This should be resolved before merge.

Enforce the documented THPDefaultConfig values in the CRD.

The generated CRD accepts any string. Add // +kubebuilder:validation:Enum=madvise;always;never and regenerate the CRD.

在 CRD 中强制执行 THPDefaultConfig 的文档取值。

生成的 CRD 接受任意字符串。请添加 // +kubebuilder:validation:Enum=madvise;always;never,并重新生成 CRD。
