[Observability Task] Architectural Design Concept of Abstract Indicator System

[Observability Task] Architectural Design Concept of Abstract Indicator System
In order for the indicator system to better serve other modules, we need to abstract and reconstruct the indicator system，Here are some current design ideas
Collectors - Event ->Data Aggregator (Optional) ->Indicator Samples ->Indicator Exporter

[可观测性任务] 抽象指标体系的架构设计概念，
为了指标系统能更好的为其他模块提供服务，我们需要再对指标体系进行抽象重构，下面是目前的一些设计思想
采集器 ----事件 ---> 数据聚合器(可选）-->指标样本--->指标导出器
