Upgrade to k8s.io/kubernetes v1.22.1

[Ashley-wenyizha]

Is this a bug fix or adding new feature?
Security patch for high Sev CVEs

What is this PR about? / Why do we need it?

1. Upgrading to k8s.io/kubernetes v1.20.11
2. Add --build_flags=--mod=mod to hack/update-gomock to work around build fail (not sure if this is recommended, let me know if there are better mitigations)

What testing is done?

wenyizha@ aws-efs-csi-driver % rm -rf vendor/ go.sum
wenyizha@ aws-efs-csi-driver % go mod vendor
wenyizha@ aws-efs-csi-driver % go mod tidy
wenyizha@ aws-efs-csi-driver % go mod verify
all modules verified

After this update, all the high risks and some medium risks from AWS enhanced ECR scanning is gone

Hi @Ashley-wenyizha. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

@wongma7

here is what I did, added go mod vendor after go mod tidy again, still giving all modules verified but no code was changed

wenyizha@  aws-efs-csi-driver % rm -rf vendor/ go.sum
wenyizha@  aws-efs-csi-driver % go mod vendor
wenyizha@  aws-efs-csi-driver % go mod tidy
wenyizha@  aws-efs-csi-driver % go mod vendor
wenyizha@  aws-efs-csi-driver % go mod verify
all modules verified
