任务支持更换绑定执行器，方便任务分组转移和管理；

doc/XXL-JOB官方文档.md

 - 9、任务暂停、删除优化，避免quartz delete不完整导致任务脏数据；
 - 10、任务回调、心跳注册成功日志优化，非核心常规日志调整为debug级别，降低冗余日志输出；
 - 11、执行器回调日志落盘方案复用RPC序列化方案，并移除Jackson依赖；
-- [迭代中]任务支持更换绑定执行器；
+- 12、任务支持更换绑定执行器，方便任务分组转移和管理；
 - [迭代中]注册中心优化，实时性注册发现：心跳注册间隔10s，refresh失败则首次注册并立即更新注册信息，心跳类似；30s过期销毁；
 - [迭代中]脚本任务，支持数据参数，新版本仅支持单参数不支持需要兼容；
 - [迭代中]提供执行器Docker镜像；
