added iostatCpu for evaluation by project

[zo3adams]

I find the output of 'iostat' to be incredibly helpful for quick glance server status - however it is not installed by default on most systems.

This fork adds cpu idle, system, and user loads to the processes dashboard. For me personally this is helpful info, but not sure how your project feels about the inclusion of non-standard tools.

Issuing a pull request just to open discussion - can revise this fork with a method to not impact index.html if iostat not installed on the system, better page style for including what's here, and to add the other helpful info from iostat (disk iops) if project maintainer is interested?

While I cannot speak for the maintainers, it is my understanding that this project intends to be a drop-in tool, with essentially no dependencies (apart from php and a web server).

However, it would be cool to see this project creating additional functionality which is only outputted in the final HTML if the server has the tools needed. This would allow for far more information to be displayed, but the dependencies would be optional rather than mandatory.

Just contributing my $0.02.

@zo3adams , your addition is awesome. Tools like iostat provide a plethora of rich stats which sys admins would love to see. However, it is not a good fit for the project. As @cyphar mentioned, this project is meant to be a drop-in, minimal dependency dashboard. Tomorrow, I plan to list a set of guidelines for the project as well as a rough roadmap which will outline this.

@cyphar , your recommendation makes a lot of sense. I will try to incorporate that style of rendering the dashboard as v1.0 gets closer.

Thanks, guys.
