Code Review

This pull request introduces the CompleteControlPlaneUpgrade functionality to the GKE container client, including necessary updates to the client library, stubs, and settings. It also adds several new configuration structures such as CustomImageInfo, RollbackSafeUpgrade, DiskIoScheduler, and KubeletCertInfo to the protobuf definitions, along with corresponding updates to native image reflection configurations and unit tests. Additionally, various documentation references for deprecated fields have been updated. I have no feedback to provide as there were no review comments.
