Error stacktrace overhaul

[Aschen]

What does this PR do?

Improve SDK stacktrace by highlighting the user code and displaying Kuzzle stacktrace as well.

How should this be manually tested?

const { Kuzzle, Http, WebSocket } = require('./index');

const kuzzle = new Kuzzle(new WebSocket('localhost'));

function executeQuery () {
  return kuzzle.query({
    controller: 'greeting',
    action: 'sayHello'
  });
}

(async () => {
  try {
    await kuzzle.connect();
    await executeQuery();
  }
  catch (error) {
    console.error(error)
  }
  finally {
    kuzzle.disconnect();
  }
})();

If Kuzzle is running in development mode then we display both stacktrace:

NotFoundError: API controller "greeting" not found.
    [...Kuzzle internal calls deleted...]

If Kuzzle is not running in development mode we display only SDK stacktrace:

[KuzzleError: API controller "greeting" not found.
