The 'httpclient-tracer' unit test cannot work properly, because "app" hasn't been initialized, we'll get an error when getting "httpclient".
The solution is to get it in "beforeStart" in the app.js to have a test with.
Add `onClientError` configuration to customize handling client error and get
`rawPacket`.
Connect timeout for 5000ms, GET https://eggjs.org/ for several times
