nfd-worker: Add support to configure the ownerReference to Node

[ozhuraki]

Closes: #2039

[k8s-ci-robot]

Hi @ozhuraki. 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.

Thanks @ozhuraki for this.

I started to wonder should we make this default behavior, instead, name the option OwnerRefPod (defaulting to false). In this case we'd also need to update the docs/deployment/uninstallation.md with instructions how to remove stale nodefeature objects. Probably update other pages as well (like docs/deployment/uninstallation.md#uninstallation) and note/warn about stale NodeFeature files after uninstallation.
