Automatic image naming is weird, change it or provide explicit naming option

I have the following docker-compose.yml:

nginx:
  build: .
  ports:
   - "80:80"

.. along with this Dockerfile in the same directory:

FROM ubuntu

RUN apt-get update && apt-get upgrade -y
RUN apt-get install -y nginx

CMD nginx && tail -f /dev/null

Now if I do "docker-compose up", I get the following image entry:

jonas@cyberman#11: docker images
REPOSITORY                         TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
nginx_nginx                        latest              70d6fcf2fc2c        29 minutes ago      261.1 MB

"nginx_nginx"? Really? You couldn't just use "nginx" as I named it?
If you really want to have such weird naming schemes, at least let me override it with a proper name.

Duplicate of #652. In summary: yes, it's annoying, but for now we rely on the naming scheme to keep track of containers. In the next version we're going to switch to using labels (see #1356) and then it'll be possible to implement support for custom container names.

@aanand Any plans to change the naming scheme in the near future via some new options or flags?

A new option in compose.yml for image_name similar to container_name that was implemented would be really nice to have.

I think to do this properly we'd want #1403, but that isn't currently possible with docker labels.

Instead of customizing the name, I think I would rather support some way of re-tagging the image to different names (something like #213). That way the "internal" names are consistent, but you can alias the image as anything you want for "external" use.

Thanks for the suggestion, @Jonast. This is covered by #213, as @dnephin suggests, and I have also created #2092 to more formally propose this feature.
