Skip copy for given container registry domain

[jetersen]

Since AWS has added more options for pull through cache on ECR.

I would prefer to use that but there a still unsupported image sources. Not all registries are supported so this provides the flexibility to skip the once ECR Pull through cache handles.

There is still a benefit to k8s-image-swapper since it supports the image swap on a pod level. Cause we want use tooling to detect changes to the images we use on a higher level than the pod.

Currently ECR supports:

• public.ecr.aws
• registry-1.docker.io
• registry.k8s.io
• quay.io
• ghcr.io
• *.azurecr.io
• registry.gitlab.com

So far we have come across other image sources we use that are not supported by ECR pull through:

• registry.opensource.zalan.do
• us-docker.pkg.dev
• xpkg.upbound.io

Been running this in production for a while and works as intended.
