[sig-apps] Daemon set [Serial] should not update pod when spec was updated and update strategy is OnDelete

[jberkus]

DaemonSet upgrades and downgrades have been failing since 9/25.

Dashboard: https://k8s-testgrid.appspot.com/sig-release-master-upgrade#gce-new-master-upgrade-master

Sample Failure: https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-kubernetes-e2e-gce-new-master-upgrade-master/1803

This test failure will block 1.13 beta, so please let's fix it before then. Thanks!

I'm investigating this.
It is related to the change here: #68754. Still figuring out the actual impact and how to fix it.

FWIW there's one more related test failure - #67903

[bradhoekstra]

This is also being discussed in this issue: #69445

Any opinions on whether the suggestion by @kow3ns here is the correct approach for fixing this?
