A previous commit has implemented `git repack --filter=<filter-spec>` to allow users to filter out some objects from the main pack and move them into a new different pack. Users might want to perform such a cleanup regularly at the same time as they perform other repacks and cleanups, so as part of `git gc`. Let's allow them to configure a <filter-spec> for that purpose using a new gc.repackFilter config option. Now when `git gc` will perform a repack with a <filter-spec> configured through this option and not empty, the repack process will be passed a corresponding `--filter=<filter-spec>` argument.
