Don't record class map objects outside of the requested scope

Given this event:

A code object will be created in the class map for org.springframework.web.filter.OncePerRequestFilter, despite that package not existing in the appmap.yml configuration.

首先跟踪所提供的事件是如何被处理的，以及 class-map 对象是如何创建的，然后检查 appmap.yml 中请求的作用域如何应用于事件的 defined_class。使用 OncePerRequestFilter 示例作为回归用例；当配置的包之外的类不再被记录时，即表示完成。
