EN In the actual business scenario, there are at least three types of businesses at the same time 1. There are activities, and the stage definition is 1-10, 11-30, 30-50, 50 +; 2. There are activities, and the stage definition is 1-20, 21-100, 100 +; 3. There is no activity, and there is no need for periodic merging; ...... In order to meet the actual complex business scenarios, I redesigned `MessageListenerStagedConcurrently` and `StageOffsetStore`,`getStageDefinitionStrategies` can now define multiple policies (such as the different definitions of the above 1 and 2 types of businesses), and support dynamic configuration. A new `computeStrategy` is added to let users choose a policy, A new `computeGroup` is added to distinguish different businesses in the same definition (such as category 1 above) (the ID of businessman a is `a` and that of businessman B is `b`). CN 在实际的业务场景中，至少同时存在3类商家： 1.有活动，且阶段定义1-10，11-30，30-50，50+； 2.有活动，且阶段定义1-20，21-100，100+； 3.无活动，不需要阶段性并法； ...... 为了满足实际复杂的业务场景，我重新设计了`MessageListenerStagedConcurrently`和`StageOffsetStore`，`getStageDefinitionStrategies`现在可以定义多个策略了(比如上面1、2类商家的不同定义)、并且支持了动态配置，新增`computeStrategy`让用户选择一种策略，新增`computeGroup`以区分同类定义(比如上面的1类)中的不同商家(商家a的id为`a`、商家b的id为`b`)。 -- This is an automated message from the Apache Git Service.
