Slightly simplify partial clone user experience

This was something discussed briefly at the contributor summit: users will have a hard time remembering git clone --filter=blob:none <url>. This series simply adds a --partial option that is equivalent to --filter=blob:none, with the ability to specify a size using --partial=<size> that is equivalent to --filter=blob:limit=<size>.

While going to the git clone documentation to add this option, I noticed that there is no reference to the --filter option there, nor any discussion of partial clone. I resolved the former.

REQUEST FOR HELP: If anyone out there is looking for an opportunity to contribute documentation, I feel there is a need to include a section in the git clone documentation devoted to partial clone. Hopefully such a section would include answers to these questions:

1. What is a partial clone?
2. Why would I want a partial clone?
3. How do I need to be careful when using a partial clone?

I don't have time to write such a document right now, which is why I'm asking for help if anyone is looking for a non-code way to contribute to the project.

Thanks, -Stolee
