Is your feature request related to a problem? Please describe:
When starting up a dev cluster using make cluster-up and make cluster-sync, some resources are deployed. Some of the resources use images outside the local registry such as from quay.io etc. If a developer/contributor works in an isolated environment that doesn't have access to those external registries the deployment will fail because it cannot pull images from those remote registries.

Describe the solution you'd like:
To solve the described issue above, one way should be to have a script to manually pull a list of
such external images into the local registry so that those resources can referencing the images from the local registry.
