pkgs to be moved to utils repo

[mengqiy]

These need to move out of k8s in order to cut kubectl out:

• [x] k8s.io/kubernetes/pkg/util/exec (PR: #5)
• [ ] k8s.io/kubernetes/pkg/util/interrupt

These should probably live in this repo, but are not required to move:

• [ ] k8s.io/client-go/util/jsonpath per https://github.com/kubernetes/kubernetes/issues/48209#issuecomment-315483101
• [ ] apimachinery/pkg/util/sets

Ref: https://github.com/kubernetes/kubernetes/issues/48209#issuecomment-314537745

Feel free to edit the list above if you have more.

We are also using k8s.io/kubernetes/pkg/util/configz in Service Catalog

These look reasonable to me. They're all part of fairly generic package names anyway (pkg/util), so it looks like they are fairly generic. One thing that is important is: are these used in multiple places? are they generally useful or are there some opinions hidden behind these names?
