docker build --pull

[tianon]

Now that moby/moby#9281 is in Docker 1.4.0, it'd be great to have either pull: true in fig.yml next to build: or have a fig build --pull!

I like how this will mean if an upstream image gets updated, then Fig environments will always be in sync.

Perhaps we should also have an option in fig.yml to enable this: #12

Yeah, I actually discovered this in surprise when I did fig pull today and realized it only pulls image: declarations and not FROMs, which was understandable but surprising behavior.

+1 I've also wanted to be able to pull base images

+1 And +1 on having this both via --pull and inside fig.yml

(Nit: shouldn't the title of this issue be _fig_ build --pull?)

@tianon I send that PR, but We need docker-py support for this feature. docker/docker-py#421

[tianon]

It's in! 👍 (and it'll be in the 0.7.0 release tomorrow: docker/docker-py#436)

+1 for docker-compose build --pull
I don't need it inside .yml file.
