Cluster upgrade stuck with AWSEBSCSIDriverOperatorCRDegraded due to `volumesnapshotclass.yaml` timeout

Issue

• Cluster with low API performance
• Encountering a blocking issue during the OpenShift cluster upgrade where the ClusterOperator Storage is degraded. The following message is repeatedly observed in the status conditions:

- lastTransitionTime: "2025-06-07T08:53:57Z"
  message: "AWSEBSCSIDriverOperatorCRDegraded: AWSEBSDriverConditionalStaticResourcesControllerDegraded:
    \"volumesnapshotclass.yaml\" (string): the server was unable to return a response
    in the time allotted, but may still be processing the request\nAWSEBSCSIDriverOperatorCRDegraded:
    AWSEBSDriverConditionalStaticResourcesControllerDegraded:"
  reason: AWSEBSCSIDriverOperatorCR_AWSEBSDriverConditionalStaticResourcesController_S

• Confirmed that the VolumeSnapshotClass resource either exists or is being created eventually, yet the operator remains in a degraded state.

• The operator still degraded after stabilizing API
