   Refer to least_conn.lua
   ```
   get = function (ctx)
               .......
               info.score = info.score + info.effect_weight
               servers_heap:update(server, info)
               return server
           end
   ```
   
   ```
           after_balance = function (ctx, before_retry)
               local server = ctx.balancer_server
               local info = servers_heap:valueByPayload(server)
               info.score = info.score - info.effect_weight
               servers_heap:update(server, info)
   ......
   ```
   
   I found that the counter will add after picking,   and  reduce in the log phase，  so this will work only for the
    http request of upgrade。  After ws upgrade，  apisix will not kown how many active tcp connections now
   
   In the product env，  we find least_conn fall back to rr through our monitor dashboard。
