Feature Request: Add option to change clone depth

[xaviergmail]

Describe the solution you'd like
I would like a new --clone-depth CLI flag added, to be passed to cloneLocalRepository's git.CloneOptions.

Describe alternatives you've considered
I also considered keeping the repositories cloned in a static non-temporary directory for faster batch operations across several repos which would be faster, but this seems easier to implement.

Additional context
This would speed up running git-xargs in our org tremendously. We have ~180 repos, only a few archived but a --dry-run --skip-archived-repos with just echo hi as the script still takes 12 minutes, presumably due to large git histories with non-LFS binary data.

@xaviergmail this sounds super reasonable. Thanks for the report. It may take us a while to get to this, but anybody is welcome to implement this and put up a PR in the meantime.

This is supported in a similar project I maintain called multi-gitter. You might want to check it out.

By default, it runs with a depth of 1. But any depth can be chosen.
