Add timeoutSeconds patch for webhook configuration

[tcnksm]

Context: #1023

Add timeoutSeconds patch for webhook configuration.

Currently, controller-tools does not support timetouSeconds marker (I'm sending patches for it). So just add kustomize patches for it.

Test

Executing the following command (which is executed in cloudbuild.yaml) on my local PC,

cd multi-tenancy/incubator/hnc
mkdir out
cd out
touch kustomization.yaml
kustomize edit add resource ../config/default
kustomize build . -o ./hnc-manager.yaml

This is the output of hnc-manager.yaml. You can see timeoutSecond is added.

Hi @tcnksm. 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.

Thanks Taichi. Would you please confirm how you tested it? Eg, did you generate the manifests, did you observe the timeout working correctly, etc?
