Add auth options to docker compose pull

[pantharius]

Hello,
It seems that if we need an auth to pull the image in the compose file in compose.js, we need to have possibility to pass options.
So my fix proposal is simple :

async pull(serviceN, options) {
    // ...
        var streami = await this.docker.pull(service.image, options);
    // ...
  }

(i'm not familiar with fork system but i mean it's just an add of 8 chars)
Regards,
