   Right now, endpoint analysis is based on the operation name of the entry span. I found there are some special cases, we need more than one endpoint for a single request analysis, typically [GraphQL](https://graphql.org/)
   
   The `/graphql` endpoint should be detected, which is reasonable, and it matches the real traffic. So, service, instance, and endpoint are matched. But, at the same time, GraphQL could be like this,
   ```graphql
   {
     r1:readMetricsValues(condition : {
       name: "service_cpm",
       entity: {
         scope: Service,
         serviceName: "projectD.business-zone",
         normal: true,
       }
     }, 
     duration: {step:MINUTE, start: "2020-05-28 1040", end: "2020-05-28 1050"}
     ) {
       label,
       values {
         values {
           id,
           value
         }
       }
     },
     
     r2:readMetricsValues(condition : {
       name: "service_cpm",
       entity: {
         scope: Service,
         serviceName: "projectA.business-zone",
         normal: true,
       }
     }, 
     duration: {step:MINUTE, start: "2020-05-28 1040", end: "2020-05-28 1050"}
     ) {
       label,
       values {
         values {
           id,
           value
         }
       }
     }
   }
   ```
   
   The user would expect the `readMetricsValues` endpoint detected, with 2 calls sharding different(or same) latency.
   
   Base on the above scenario, I want to add `x-le`(extension logic endpoint) series tag(s)
   - Tag key `x-le`, value is JSON format. `name:xxx, latency:yyy`.
   
   Same as other tags in SkyWalking, we could have multiple tags with the same key. Such as in the above case, there should be two tags with values like this
   ```json
   {
     "name": "readMetricsValues",
     "latency": 100
   }
   ```
   
   NOTICE, this endpoint traffic would not be added into the instance or service level, to keep those two traffic data as same as the real network call. And there is no endpoint dependency for logic endpoints.
