Ability to display non-allocated resources

[h0tbird]

I would like to be able to display non-allocated (non-requested) resources (allocatable - allocated)
This is useful to better understand why the scheduler is not able to schedule a pod due to lack of allocatable resources.
Great tool, thank you!

Hey @h0tbird, this is a great idea! I think this would work well with #36. There's so many potential columns to display, we may need to think through how we could limit them. Any ideas for what this flag might be called? Maybe this is --available?

I made a first pass at this in a new MR: #37.. I don't like the way I've done it, but thought I'd raise the MR to open discussion first.

@robscott how about to close this issue because of #37 ?
