V2 Refactor: Core Components using Dependency Injection, Middlewares and Services

[FerdinandSu]

Thoroughly refactor the core components, imitating [MobileSuit](https://github.com/hit-refresh/mobilesuit]'s approach based on dependency injection, middleware, and service registration to complete the current core functions; The main case code for this part of the reference project is located in HitRefresh.MobileSuit.Core, therefore the relevant components of JMobileSuit should be located in package ReFreSH.JMobileSuit.Core.

彻底重构核心组件，模仿MobileSuit基于依赖注入、中间件和服务注册的方式完成当前的核心功能；参考项目的这部分主要案例代码位于HitRefresh.MobileSuit.Core，故JMobileSuit的相关组件应该位于package ReFreSH.JMobileSuit.Core.
