[scheduler]
driver=filter_scheduler 调度驱动有四种，filter_scheduler(缺省)，caching_scheduler(不推荐，未来废弃），chance_scheduler(随机调度，不推荐，未来废弃），fake_scheduler（假借的，用于测试）
discover_hosts_in_cells_interval=300 增加计算节点时，刷新时间间隔，负数(-1)时不刷新，即增加节点不能自动加入集群。
max_placement_results=1000 实例放置的位置，只用于filter_scheduler,小于等于可用的物理计算节点数，默认1000，最小1
workers=默认是可用的cpu总数，最小为0
limit_tenants_to_placement_aggregate=false 限制租户到主机聚合中
placement_aggregate_required_for_tenants=False，limit_tenants_to_placement_aggregate=True时该参数起作用
