If you want to cherry-pick this change to another branch, please follow the instructions <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/cherry-picks.md">here</a>. code-generator: unify generator main funcs and prepare for launching from one binary - remove "generated by client-gen with custom arguments" message as this does not make sense in the times of k8s.io/code-generator - unify generator main funcs and explicitly call pflag.AddFlags and pflag.Parse. This will allow to instantiate the generators also from other places. Requires https://github.com/kubernetes/gengo/pull/80. Closes https://github.com/kubernetes/kubernetes/issues/53522.
