Discovery for group import/export
Zendesk issue: https://gitlab.zendesk.com/agent/tickets/15717 Related to gitlab-ce#3050
Allow a user to export all projects within a group. Bundle it as one downloadable archive. This depends on gitlab-ce#3050 being complete.
This is a design discovery issue building on the MVC being developed in &1952. The outcome of this issue will be a design approach for how we handle group imports in GitLab.
