As a CI engineer, I would like to be notified when images in quay.io/community-e2e-images doesn't properly support multi-arch.

This story follows up from https://issues.redhat.com/browse/OCPBUGS-16715. In this bug we discovered a cascading set of issues when the mirror job of our CI images only mirrored content for x86_64. We should be able to use something akin to the code in that issue to detect these kinds of issues early:

image-scan.sh

pushd origin; git fetch origin; git checkout $release; popd

test_dir="image-scan-"$release
rm -rf $test_dir; mkdir $test_dir

while read line; do
   [[ $line =~ ^#.* ]] && continue

   image_src=$(echo $line | cut -d ' ' -f1)
   image_dst=$(echo $line | cut -d ' ' -f2)
   rm -f $test_dir/src.txt $test_dir/dst.txt

   podman manifest inspect $image_src > $test_dir/src.txt
   podman manifest inspect $image_dst > $test_dir/dst.txt

   result=0   
   diff $test_dir/src.txt $test_dir/dst.txt || result=$?
   case $result in
   1) echo "BAD IMAGE: $line" ;;
   0) echo "GOOD IMAGE: $line" ;;
   *) echo "ERROR: diff failed for $line"
   esac
done < $file

rm -r $test_dir

It should be noted that we will need to maintain a skip list for image checks, since the pause image in 4.13 and above will not have a matching signature do to forced image compression in quay.io. Alternatively, for images that fail, we can fall back to checking how they would dry-run mirror via skopeo and using that to do the validation:
`BAD IMAGE: registry.k8s.io/pause:3.9 quay.io/openshift/community-e2e-images:e2e-28-registry-k8s-io-pause-3-9-p9APyPDU5GsW02Rk`
