🐛 Allow building a fake client with graceful deleting Pods

[arkbriar]

The change here allows user to build a fake client with graceful deleting Pods, which have their .metadata.deletionTimestamp set and have no finalizers. This is a special case allowed in the kube-apiserver.

The PR reflects the behaviour precisely according the strategy code from Kubernetes.

It should fix the #2359.

Hi @arkbriar. 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.

Hi @vincepri, thanks for unblocking the test. It seems that @lleshchi can not be assigned, could you help assign another folk who's willing to review?

Besides, can you help review the changes? @alvaroaleman Much appreciate.

[arkbriar]

@arkbriar: The following test failed, say /retest to rerun all failed tests or /retest-required to rerun all mandatory failed tests:

Test name Commit Details Required Rerun command pull-controller-runtime-test 0cf3b4c link true /test pull-controller-runtime-test Full PR test history. Your PR dashboard. Please help us cut down on flakes by linking to an open issue when you hit one in your PR.

Looks like it was caused by a flaky test. Let me rerun it.

/retest

Hi @FillZpp, thanks for your review. I have revised the code as you suggested. Would you mind taking a another look?f
