Document the need to use a PAT with Registry when 2FA is on

GitLab 8.12 introduced a new permissions model which tightened the
security of Container Registry. It is now required to use a personal
token if 2FA is enabled.

Some things you should be aware of when using the Container Registry:
* You must log in to the container registry before running commands. Putting this in `before_script` will run it before each build job.
* Using `docker build --pull` makes sure that Docker fetches any changes to base images before building just in case your cache is stale. It takes slightly longer, but means you don’t get stuck without security patches to base images.
* Doing an explicit `docker pull` before each `docker run` makes sure to fetch the latest image that was just built. This is especially important if you are using multiple runners that cache images locally. Using the git SHA in your image tag makes this less necessary since each build will be unique and you shouldn't ever have a stale image, but it's still possible if you re-build a given commit after a dependency has changed.
* You don't want to build directly to `latest` in case there are multiple builds happening simultaneously.

With the update permission model we also extended the support for accessing

As GitLab Runner 1.6 doesn't yet incorporate the introduced changes for
permissions, this makes the `image:` directive to not work with private projects

private images. We plan to remove that limitation in one of the upcoming releases.
