Subject: [PATCH] handle factoryCreate fail

if don't  do this ,it would  call  factory.create() again and again . or I can do like this outside.
const pool = genericPool.createPool(factory, options);
  pool.on('factoryCreateError', function (err) {
    const clientResourceRequest = pool._waitingClientsQueue.dequeue();
    if (clientResourceRequest) {
      clientResourceRequest.reject(err);
    }
  })
Need change _waitingClientsQueue -> waitingClientsQueue and defined Pool.FACTORY_CREATE_ERROR = FACTORY_CREATE_ERROR;
