Create New Project using another project as the source
Description
When creating a new Project in GitLab, it would be helpful to have the ability to use another Project as the seed/source. Recently I was tasked with creating new, unique Projects using a branch of an existing project as the starting files. I could not accomplish this within the GitLab UI, so I needed to first create a blank new project, then use CLI commands to push another project's branch in as "master".
Proposal
In the New Project screen, allow selecting an existing Project and branch name to seed the new Project's master branch. Possibly allow selecting additional branches from an existing project to seed new branches in the new Project.
