Consider custom router ?

Is your feature request related to a problem? Please describe.

I’m using egg.js to develop project. In this project, I want to use apm to monitor performance which from fronted to backend service.

In this project apm can not naming transaction with pathname, because of apm use http module, but egg.js use a module forked from koa-router

Describe the solution you’d like

Egg.js fork koa-router and rename egg-router, they add some additional features, but not change the property. So apm can use koa-router module to parse request in egg.js in theory. I notice that, it do judge with package name in Instrumentation. So can add a parameter like customRouterMap, for exmaple:

  customRouterMap: {
    "@eggjs/router": {
        name: "koa-router",
        version: "7.4.0"
    }
  }

put it in start func, then apm can use koa-router module to naming transaction.

There has a simple implementation in my fork.

Please checkout whether it is feasible .
