        """实时查询 Agent 状态信息，并填充到主机信息列表"""

筛选逻辑带有 Agent 状态 如何处理？

[CohleRustW]

实现方案

实现方向

1. 全量拉取时不去更新主机状态，只在分页场景下刷新主机状态
2. 当筛选条件包含 Agent 状态/版本 时，不刷新主机状态

代码实现

1. multiple_cond_sql 增加参数判断是否进行状态表的级联查询
2. 补充update_or_create_host_agent_status 返回主机实时状态和版本信息映射表
3. 回填查询到不带主机状态信息的结果中的主机状态和版本信息

自测结果

填充 Agent 数据前，本地测试代码中增加破坏数据

ProcessStatus.objects.filter(name=ProcessStatus.GSE_AGENT_PROCESS_NAME, bk_host_id__in=bk_host_ids).update(status="TERMINATED")

1. 当 fill_agent_state_info_to_hosts 异常时

2. 当长度超过 QUERY_AGENT_STATUS_HOST_LENS 时

3. 正常获取 Agent 状态的情况下
