Describe the proposal

EN: Currently, version 3.2 already supports index data burying, and supports data burying to be sent to the Prometheus time-series database system through custom ports, push gateways and spring boot endpoints, in order to make Dubbo users more friendly to use The monitoring of these indicators requires us to make a graphical display panel of these indicators. Currently, the panel display uses Grafana to query Prometheus data. The template made with Grafana can be uploaded to Grafana's official dashboard library to facilitate Dubbo users. It can be imported with one click without complicated configuration.

中文：目前在3.2的版本已经支持了指标数据的埋点，并且支持数据埋点通过自定义端口，推送网关和spring boot 端点的形式输送给普罗米修斯时序数据库系统，为了让Dubbo用户更友好的使用这些指标监控，需要我们制作好这些指标的图形化展示面板，目前面板的展示使用Grafana来查询普罗米修斯数据即可，使用Grafana制作好的模板可以上传至Grafana官方的dashboard库来方便Dubbo用户可以一键导入无需复杂的配置。
