Port repository backup/restore to use GlRepository

What does this MR do?

• Ports rake gitlab:backup:create and rake gitlab:backup:restore to use GlRepository
• GlRepository allows us to generically interface with git repositories without needing to have any special logic to handle different repository types (project, wiki, design, snippet, etc)
• Design repos will be handled in #233430 (closed)
• Snippet repos will be handled in #233626 (closed)

Verify repository backups

Remove all the empty directories as the logic was not consistent previously and it will clutter up the diff:

$ find 1600379592_2020_09_18_13.4.0-pre_gitlab_backup/repositories -type d -empty -delete
$ find 1600379433_2020_09_18_13.4.0-pre_gitlab_backup/repositories -type d -empty -delete

Now diff repos:

$ diff -qr 1600379433_2020_09_18_13.4.0-pre_gitlab_backup/repositories 1600379592_2020_09_18_13.4.0-pre_gitlab_backup/repositories

No output == success 🎉

Restore backup with this MR

Now that we know the backups taken are identical we only need to restore once using this MR to verify it works. I setup a fresh GDK to restore the backup into.

$ cp ../../gdk/gitlab/tmp/backups/1600379433_2020_09_18_13.4.0-pre_gitlab_backup.tar tmp/backups/
$ be rake gitlab:backup:restore
Unpacking backup ... done
Be sure to stop Puma, Sidekiq, and any other process that
connects to the database before proceeding. For Omnibus
installs, see the following link for more information:
https://docs.gitlab.com/ee/raketasks/backup_restore.html#restore-for-omnibus-gitlab-installations

Before restoring the database, we will remove all existing
tables to avoid future upgrade problems. Be aware that if you have
custom tables in the GitLab database these tables and all data will be
removed.

Do you want to continue (yes/no)? yes
