These commands update the new 'maintenance.repos' config option in the global config so the background maintenance job knows which repositories to maintain. These commands allow users to add a repository to the background maintenance list without disrupting the actual maintenance mechanism. For example, a user can run 'git maintenance register' when no background maintenance is running and it will not start the background maintenance. A later update to start running background maintenance will then pick up this repository automatically. The opposite example is that a user can run 'git maintenance unregister' to remove the current repository from background maintenance without halting maintenance for other repositories.
