Adopt existing git directories

If directories containing bare git repositories exist in the [repository].ROOT hierarchy, they can be imported using the admin panel.

• Make sure the directory names are lowercase.
• [repository].ROOT/{user,org}/{repo}.git will become a project owned by the user or the org.
• Go to /admin/repos/unadopted
• In trusted environments, users can also be given similar permissions via the ALLOW_ADOPTION_OF_UNADOPTED_REPOSITORIES setting.
