Some workloads (OVN raft, LINSTOR controller) fail when replicas start
at different times due to image-pull stagger across nodes. Add a
DaemonSet-based pre-pull step that runs before helm install, ensuring
all nodes have the images cached so every replica starts within
milliseconds of each other.
The script accepts image refs on stdin and creates one container per
image (parallel pulls, total time = max of any single image rather than
sum). The bats test sources images directly from the rendered charts
via yq, walking only PodSpec-shaped objects so version bumps stay in
sync automatically without a separate hardcoded list.
