Add the verify-codegen.sh into CI pipeline

[Jeffwan]

🚀 Feature Description and Motivation

We should add ./hack/verify-codegen.sh to the CI pipeline, if there's any API spec change, we should generate the clientset in the same PR.

before we add to the pipeline, we need to resolve an issue

Seems it tries to delete the zz_generated.deepcopy.go file which conflicts with make generate. We need to adjust update-codegen.sh to address such issue.
