From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>
In preparation for launching background maintenance from the 'git
maintenance' builtin, create register/unregister subcommands. 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.

are specified, then those tasks are run in that order. Otherwise,

+ Remove the current repository from background maintenance. This
