Airgap support

[jpic]

Airgap deployments happen on networks without internet access, with a private registry.

It would be great if we had the following commands:

• kustomize airgap pull: to pull all images
• kustomize airgap prefix <your.registry/your.path>: this would do kustomize edit set image <each image>=<prefix>/<each image and add the new tag to all images
• kustomize airgap push <your.registry/your.path>: push all retagged images to the private registry

Additionally, repos like kubeflow should be able to hook additional images, ie. for situations like this

Kustomize exclusively deals with Kubernetes configuration files: to Kustomize, images are just a field--pushing, pulling or otherwise handling the images themselves is out of scope for this tool.

Regarding making Kustomizations work without internet access in general, you may be interested in this issue: #3980.

If I've misunderstood, please reopen with more detail.
