[Feature Request] Add CPU Processes

[alvins82]

Required prerequisites

• [X] I have searched the Issue Tracker that this hasn't already been reported. (comment there if it has.)
• [X] I have tried the latest version of nvitop in a new isolated virtual environment.

Motivation

Would like to be able to also see top CPU processes also alongside the GPU processes. Otherwise need to run 'top' to get that output. Rather run one command to see everything.

Solution

Would be good to add the CPU processes just like GPU processes section.

I do use nvitop-exporter to monitor some gpu servers. But some of my users run cpu jobs at gpu servers. In checking what is creating that high node load I need to login to server and check, if it is a cpu only job. If nvitop-exporter could export cpu jobs aswell I wouldn't need to check or need to setup another cpu exporter.
