服务器下线时，如果正常执行spring 自带的destroy()方法，执行器会向xxljob admin 发送一个http请求，最终执行com.xxl.job.admin.core.thread.JobRegistryHelper#registryRemove方法，该方法会在registry表中把当前节点去掉，但是不会更新group表，而实际调度是根据group表中的address_list来选择pod。group表中的地址信息是30s更新一次。所以最快也要30s。如果destroy()方法没有执行，只能等xxljob admin 90s没有收到心跳，再去registry表中把当前节点去掉，再更新group表。建议1、com.xxl.job.admin.core.thread.JobRegistryHelper#registryRemove方法中同步更新group表。
2、如果多次因为网络调度失败，将当前节点排除。
