   ### Describe the bug
   
   I have testing it at my local dev environment.
   First, `cd <kyuubi_project_folder>`
   then add following config to `conf/kyuubi-defaults.conf`:
   ```
   kyuubi.frontend.protocols THRIFT_HTTP
   ```
   then `bin/kyuubi start`.
   Check metric with command `grep "thrift" work/metrics/report.json -A3`:
   ```
       "kyuubi.thrift.http.connection.opened" : {
         "count" : 1
       },
       "kyuubi.thrift.http.connection.total" : {
         "count" : 1
       }
     },
   
   ```
   => opened and total should be 0
   
   then run `bin/beeline -u "jdbc:hive2://10.xxx.xx.xxx:10010/default;transportMode=http;httpPath=cliservice"`,
   check metric again:
   ```
   "kyuubi.thrift.http.connection.opened" : {
         "count" : 1
       },
       "kyuubi.thrift.http.connection.total" : {
         "count" : 1
       }
     },
   
   ```
   => open and total should be 1
   
   open another terminal and run `bin/beeline -u "jdbc:hive2://10.xxx.xx.xxx:10010/default;transportMode=http;httpPath=cliservice"`, check metric again:
   ```
   "kyuubi.thrift.http.connection.opened" : {
         "count" : 1
       },
       "kyuubi.thrift.http.connection.total" : {
         "count" : 1
       }
     },
   ```
   => open and total should be 2
