Add additional information to `kp image list` output to help users identify particular apps

Requested by Kathy Wan (VMware Tanzu SE) in a user interview

As an opps person using kp I want additional information about each kpack image when performing a list command other than just the name of the image So that I can at a glance have more context about the application that the image name represents

The idea we discussed was turning kp image list into tabular output and provide the user that created the image, and the "kind" of app (programming language)
