Feature request: kustomize support

[lukasmrtvy]

Is your feature request related to a problem? Please describe.
Would be great to have kustomize support https://github.com/kubernetes-sigs/kustomize
Its already implemented in kubectl client and I think its worth to have it.

Describe the solution you'd like to see
Handle:

• template $overlay_file
• kubectl kustomize . > $file
• kubectl apply -f $file
  or
• template $overlay_file
• kubectl build base | kubectl apply -f
  or
• template $overlay_file
• kubectl apply -k base

Describe alternatives you've considered
null_resource with local-exec may be a way
