Code Review

This pull request updates the generated Java client library for the Google Cloud Container service. The changes include adding support for the CompleteControlPlaneUpgrade method, updating documentation strings, adding new fields to ClusterUpdate (such as desiredEmulatedVersion and desiredRollbackSafeUpgrade), and adding new fields to NodePool (such as kubeletCertInfo) and NodePoolUpgradeInfo (such as customImageInfo). Additionally, several deprecation notices were updated to reflect new line numbers in the source proto file. There are no review comments to address.
