_plugin_id_应用场景为区分多个网关的插件日志，插件配置中需额外指定_plugin_id_字段，如不指定，默认为nil，配置示例：

_plugin_id_: sdqwdacscfqw21
_rules_: ...
...

调整后插件日志格式示例如下：

// 启动失败日志
[ai-statistics] [sdqwdacscfqw21] [nil] plugin start failed
// 启动成功日志
[ai-statistics] [sdqwdacscfqw21] [nil] plugin start successfully
// 业务请求日志
[ai-statistics] [sdqwdacscfqw21] [1ce56bf7-891c-9d8f-90a2-d714b89bdfb3] get usage information failed, skip metric record

进一步，在日志中可通过正则提取 plugin_id 以及 request_id 构建索引以供查询
