需求

目前 OpenSergo 控制面的日志机制非常简单，复用了 Sentinel Go 的日志模块。我们需要设计一个通用的 logger 机制与基本实现，并支持任意扩展。

功能分析

日志级别，debug，info，warn，error，panic，fatal
打印方式，console 或 json

既提供全局默认log，也支持自定义传参
兼容标准库中的log
带 keyandvalues 的 log
兼容zap，logrus，klog，grpc 等log
otel 支持，即带 context log
动态更改日志级别
console 中支持颜色显示
error 等级别支持发送到监控系统或触发报警
高性能

概要设计

基于zap封装，达到高性能（更少的内存分配及非sugar log 未使用反射）
