自v1.5版本之后, 任务取消了"任务执行机器"属性, 改为通过任务注册和自动发现的方式, 动态获取远程执行器地址并执行。
AppName: 每个执行器机器集群的唯一标示, 任务注册以 "执行器" 为最小粒度进行注册; 每个任务通过其绑定的执行器可感知对应的执行器机器列表;
Beat: 任务注册心跳周期, 默认15s; 执行器以一倍Beat进行执行器注册, 调度中心以一倍Beat进行动态任务发现; 注册信息的失效时间被两倍Beat;
注册表: 见"XXL_JOB_QRTZ_TRIGGER_REGISTRY"表, "执行器" 在进行任务注册时将会周期性维护一条注册记录，即机器地址和AppName的绑定关系; "调度中心" 从而可以动态感知每个AppName在线的机器列表;
执行器注册: 任务注册Beat周期默认30s; 执行器以一倍Beat进行执行器注册, 调度中心以一倍Beat进行动态任务发现; 注册信息的失效时间被三倍Beat;
执行器注册摘除：执行器销毁时，将会主动上报调度中心并摘除对应的执行器机器信息，提高心跳注册的实时性；
为保证系统"轻量级"并且降低学习部署成本，没有采用Zookeeper作为注册中心，采用DB方式进行任务注册发现；

- 3、新增JFinal类型执行器sample示例项目；
- 4、执行器手动设置IP时将会绑定Host；
- 5、项目主页搭建，提供中英文文档；
- 6、执行器回调线程优化，线程销毁前批量回调队列中所有数据；

### TODO LIST
- 1、任务权限管理：执行器为粒度分配权限，核心操作校验权限；
