Merge pull request #48065 from ironcladlou/unstructured-field-fix

Automatic merge from submit-queue (batch tested with PRs 48183, 45611, 48065) Fix Unstructured field accessor Fix the Unstructured GetDeletionGracePeriodSeconds accessor which was always returning nil regardless of the underlying stored value. The field value always appearing nil prevents Custom Resource instances from being deleted when garbage collection is enabled for CRs and when DeletePropagationOrphan is used. More generally, this fix means that delete-on-update now works for CR instances. Add some test coverage for Unstructured metadata deserialization. The Unstructured DeletionGracePeriodSeconds field marshals as a value type from JSON and as a pointer type via SetDeletionGracePeriodSeconds. The GetDeletionGracePeriodSeconds method now supports handling both int64 and *int64 values so that either underlying value can be returned. Add a reflection-based unit test which attempts to exercise all the Object Get/Set methods for nil handling. ```release-note Registries backed by the generic Store's `Update` implementation support delete-on-update, which allows resources to be automatically deleted during an update provided: * Garbage collection is enabled for the Store * The resource being updated has no finalizers * The resource being updated has a non-nil DeletionGracePeriodSeconds equal to 0 With this fix, Custom Resource instances now also support delete-on-update behavior under the same circumstances. ```
