Automatic merge from submit-queue Change what is stored in DaemonSet history `.data` **What this PR does / why we need it**: In DaemonSet history `.data`, store a strategic merge patch that can be applied to restore a DaemonSet. Only PodSpecTemplate is saved. This will become consistent with the data stored in StatefulSet history. Before this fix, a serialized pod template is stored in `.data`; however, seriazlized pod template isn't a `runtime.RawExtension`, and caused problems when controllers try to patch the history's controller ref. **Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes #47008 **Special notes for your reviewer**: @kubernetes/sig-apps-bugs @erictune @kow3ns @kargakis @lukaszo @mengqiy **Release note**: ```release-note NONE ```
