The 'git maintenance (register|start)' subcommands add the current repository to the global Git config so maintenance will operate on that repository. It does not specify what maintenance should occur or how often. To make it simple for users to start background maintenance with a recommended schedlue, update the 'maintenance.strategy' config option in both the 'register' and 'start' subcommands. This allows users to customize beyond the defaults using individual 'maintenance.<task>.schedule' options, but also the user can opt-out of this strategy using 'maintenance.strategy=none'.
