docker/info use format JSON
Created by: Dasio
- use host CPU from Host property if available
This partially fix https://github.com/sourcegraph/src-cli/issues/855
Test plan
I have run unit tests. Also tried it locally with my podman. Still getting some error regarding volumes and tmp files. But that seems more related to podman itself probably.
I need someone to test it also with docker. If it's still work.
- tested, it should work
