Retry more error conditions in ILB e2e test

[nojnhuh]

What type of PR is this?
/kind flake

What this PR does / why we need it:

The API server ILB e2e test creates a DaemonSet to test the ILB but fails immediately if not all of those Pods exist by the time it lists them for the first time. Since the DaemonSet will create the Pods asynchronously, this PR makes that check retriable.

This should address flakes we've seen in that test lately: https://storage.googleapis.com/k8s-triage/index.html?date=2025-10-24&pr=1&text=expected%20number%20of%20worker%20node-debug%20daemonset%20pods%3A&job=azure

I didn't try this locally, so I'd like to get a few runs of the optional job in to make sure this flake is gone.
