Current behavior

@Module({})
class AppModule implement OnModuleInit {
  async onModuleInit() {
    console.log('before init')
    await somePromise()
    console.log('after init')
  }
}

(async () => {
  console.log('before')
  const app = await NestFactory.create(AppModule)
  await app.listen(3000)
  console.log('after')
})()

current log

before
before init
after
after init

Expected behavior

should log

before
before init
after init
after

What is the motivation / use case for changing the behavior?

Sometimes, I write a few async bootstrap codes in onModuleInit. I want to wait for all of the codes in onModuleInit finished before listen. Can support async hook?
