Feature Proposal: Allow pulling issues and pull requests for project being pushed to GitHub.
Issue gitlab-org/gitlab-ee#116 is planned to be included in 8.6. I suspect many projects will use it to push their code to GitHub, like GitLab itself is already doing. I think one great feature would be (if at all possible) to allow pull requests, and possibly issues, to be imported at the same time, like is currently possible when creating a project.
