1. 增加com.alibaba.cola.statemachine.StateMachine#verify方法 用来判断当前状态能否响应某个事件 2. 增加com.alibaba.cola.statemachine.builder.StateMachineBuilder#setFailoverCallback 用来增加在状态流转没有命中当前配置的规则时执行的回调 接口定义 com.alibaba.cola.statemachine.builder.FailoverCallback 默认为NumbFailoverCallbackImpl，与当前行为一样，什么都不做。 另外内置AlertFailoverCallbackImpl，用于抛出异常TransitionFailoverException
