Merge pull request #43465 from kargakis/update-validation

Automatic merge from submit-queue Disable readyReplicas validation for Deployments Because there is no field in 1.5, when we update to 1.6 and the controller tries to update the Deployment, it will be denied by validation because the pre-existing availableReplicas field is greater than readyReplicas (normally readyReplicas should always be greater or equal). Fixes https://github.com/kubernetes/kubernetes/issues/43392 @kubernetes/sig-apps-bugs
