When trying to build the s390x image, it would fail when running the apk
command with the following error:
ERROR: Unable to open root: Bad address
ERROR: Failed to open apk database: Bad address
This can be fixed by updating the third_party/multiarch/qemu-user-static/register/register.sh
and third_party/multiarch/qemu-user-static/register/qemu-binfmt-conf.sh scripts
and their usage to a newer version [1].
Additionally, the packages nginx-mod-http-lua and nginx-mod-http-lua-upstream
cannot be found in the regular http://dl-cdn.alpinelinux.org/alpine/v3.9/main/s390x/
repository, but we can use an older one [2].

All images used by e2e tests must use templates in order to allow
relocation. In addition this is hitting Dockerhub which will be
getting throttled soon.
This fixes a bug that occurred when a Service was rapidly recreated.
This relied on an unfortunate series of events:
1. When the Service is deleted, the EndpointSlice controller removes it
from the EndpointSliceTracker along with any associated EndpointSlices.
2. When the Service is recreated, the EndpointSlice controller sees that
there are still appropriate EndpointSlices for the Service and does
nothing. (They have not yet been garbage collected).
3. When the EndpointSlice is deleted, the EndpointSlice controller
checks with the EndpointSliceTracker to see if it thinks we should have
this EndpointSlice. This check was intended to ensure we wouldn't
requeue a Service every time we delete an EndpointSlice for it.
This adds a check in reconciler to ensure that EndpointSlices it is
working with are owned by a Service with a matching UID. If not, it will
mark those EndpointSlices for deletion (assuming they're about to be
garbage collected anyway) and create new EndpointSlices.
For external CA users that have prepared the kubeconfig files
for components, they might wish to provide a custom API server URL.
When performing validation on these kubeconfig files, instead of
erroring out on such custom URLs, show a klog Warning.
This allows flexibility around topology setup, where users
wish to make the kubeconfigs point to the ControlPlaneEndpoint instead
of the LocalAPIEndpoint.
Fix validation in ValidateKubeconfigsForExternalCA expecting
all kubeconfig files to use the CPE. The kube-scheduler and
kube-controller-manager now use LAE.
