个数控制是不是也在控制缓存里的？不应该只是控制去直接操作系统交互的吗

缓存是为了计算增量的CPU使用率，前一次和后一次的top n进程可能不一样，所以需要保存所有的

std::unordered_map<std::string, bool> mRegisteredCollectorMap;
std::unordered_map<std::string, std::shared_ptr<BaseCollector>> mCollectorInstanceMap;
这两个变量有点不合理。
包括
1、HostMonitorInputRunner::GetCollector的使用上。应该是自闭环合法性
2、锁的关系等
3、RegisterCollector 操作的变量是 mCollectorInstanceMap，但是另一个没操作的变量却叫reg
可能的优化
1、保持现有逻辑。一组功能不用过多发散变量，以上改成一个map。value用结构体表示。整体实现结构优化下。
2、UpdateCollector时再注册ProcessEntityCollector实例，这样能省一个变量。
