WalkthroughKMS plugin state now uses an internal wrapper that stores provider configuration and plugin image. Encoding, secret persistence, controllers, sidecar construction, and encryption tests now use this wrapper. ChangesKMS internal configuration flow
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The change can reject existing persisted KMS configuration during upgrade and can fail to apply image-only updates to the plugin sidecar, potentially leaving encryption management unable to restore state or running an outdated plugin image. These are high-impact merge-readiness risks that should be resolved before merging. Suggested reviewers: 🚥 Pre-merge checks | ✅ 15✅ Passed checks (15 passed)

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Propagate image-only changes without rotating the encryption key.
Line 579 compares only latestKey.KMS.Plugin.Plugin. sameProviderInstance therefore ignores KMSPluginImage. If only the image changes, this path returns a no-op and retains the old image stored at Lines 328-331. The sidecar builder uses the persisted KMSPluginImage, so it does not update the sidecar container image.
Reconcile and persist an image-only change independently from KMS key rotation. Add a regression test that changes only the image and verifies that the generated sidecar uses the new image.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Preserve decoding compatibility with previously stored KMS data.
The new decoder only accepts the internal envelope format, while existing Key Secrets and encryption-config Secrets were written using the previous config.openshift.io/v1 APIServer envelope with spec.encryption.kms. After an upgrade, those stored values can be rejected before reconciliation restores KMS state. Add a legacy decode fallback that converts the previous format into state.InternalKMSPluginConfig, with fixtures covering both persisted formats.

We are planning to remove image field from KMSPluginConfiguration in openshift/api (ref: openshift/enhancements#2082), since it will be populated by the OLM operators and stored in ConfigMap.
However, encryption controllers still need to carry this image field along to plugin lifecycle. This PR introduces new encodable/decodable internal API type which is derived from KMSPluginConfiguration but extended with image field.
