beforeShutdown in example should return new Promise

[peterkuiper]

Should be:

function beforeShutdown () {
  // given your readiness probes run every 5 second
  // may be worth using a bigger number so you won't
  // run into any race conditions
  return new Promise(resolve => {
    setTimeout(resolve, 5000)
  })
}
terminus(server, {
  beforeShutdown
})

or ES6:

const beforeShutdown = () => new Promise(resolve => setTimeout(resolve, 15000));

I'm also trying to figure out where beforeShutdown() fits in. I have beforeShutdown, onSignal and onShutdown set. beforeShutdown is run before onSignal. I would expect:

onSignal -> beforeShutdown -> onShutdown

onSignal would allow me to the actual logging (without a delay) and pre-cleanup steps that wouldn't interfere with serving traffic. I would then do my cleanup in beforeShutdown so onShutdown can be safely called.

Does this make sense?

@peterkuiper can you send a PR to fix the docs?

[peterkuiper]

@gergelyke I will send the PR on monday. I'll also take a look at the examples, I think those also miss the 'new Promise'.

Cool, thanks a lot @peterkuiper!
