Create registrySync.sh script to sync images between the public sources and repo1

This ticket will create a 'utils' folder at the root directory containing the below resources required in order to sync container images between the public sources for the kubevirt images and repo1.

• Create a registrySync.sh script and compose a skopeo command to sync the images
• Create a skopeo-kubevirt-sync.yaml file declaring where the kubevirt images are located
• Create a README in the 'utils' directory outlining how the script works and how to make image updates
• Test that the script works
• Create MR
