egg-mongoose: no timeout or retry if mongoose failed to connect on start

[legendecas]

• Node Version: 9.11.1
• Egg Version: 2.6.1
• Plugin Name: egg-mongoose
• Plugin Version: 2.2.0
• Platform: macOS
• Mini Showcase Repository:

while using default config like

module.exports = {
 mongoose: {
    clients: {
      db: {
        url: 'mongodb://localhost:27017/notebook',
        options: {}
      }
    }
  }
}

and run egg-scripts start without a valid mongodb running on locallost, egg would not run web workers since egg-mongoose did not connect to mongodb instance yet. And there is no timeout for egg-mongoose's start connect, egg-scripts will not exit with non-zero code yet web workers did not run, and egg stuck.

Now if we start the mongodb instance, egg will not recover to start web workers.

Referring to issue No retries are made after "failed to connect on first connect", errors on first connection shall be re-thrown so that egg will exit with the error in time.

@zhangming0305 it can be assured it's not an issue related to the mongodb url

@legendecas i suggest you to create minimal runnable github project that we can reproduce the same error.
