URL: https://github.com/apache/brpc/issues/2082

   **Describe the bug (描述bug)**
   通过brpc_metrics接口获取mbvar 转化来的多lables guage打点，提示type非法
   具体的值:
   # HELP 
lat_rank_score_total_latency{system="unknown",module="unknown",server="rank_server_nbase",status="0"}
   # TYPE 
lat_rank_score_total_latency{system="unknown",module="unknown",server="rank_server_nbase",status="0"}
 gauge
   
lat_rank_score_total_latency{system="unknown",module="unknown",server="rank_server_nbase",status="0"}
 22
   
   **To Reproduce (复现方法)**
   typedef bvar::MultiDimension<bvar::LatencyRecorder> MLatencyRecorder;
   MLatencyRecorder lat_rank_score_total("lat_rank_score_total", {"system", 
"module", "server", "status"});
   mbvar_dump=true
   mbvar_dump_format= prometheus
   
   打点收集，然后prometheus收集组件通过 http://$ip:$port/brpc_metrics获取打点结果，提示错误
   invalid metirc type "system=\"square\" ****** gauge"
   
   
   **Expected behavior (期望行为)**
   能正常收集
