fix: add kubelet tag in task of Fetch facts to avoid kubelet config inconsistencies

What type of PR is this?

/kind bug

What this PR does / why we need it:
When I ran playbook with option --tags=kubelet to update kubelet config, I found that some other configurations have been unintentionally modified. In my case, resolvConf was changed from /run/systemd/resolve/resolv.conf to /etc/resolv.conf

< resolvConf: "/etc/resolv.conf"
---
> resolvConf: "/run/systemd/resolve/resolv.conf"

I added a debug task before task(Write kubelet config file) and discovered that the variable kube_resolv_conf was't set to /run/systemd/resolve/resolv.conf.

TASK [kubernetes/node : debug] 
ok: [node1] => {
    "kube_resolv_conf": "/etc/resolv.conf"
}

After reviewing the relevant code, I found in role of kubernetes/node, some variables are overrided during task(Fetch facts), which will be used in later tasks.
So I add a tag kubelet in task(Fetch facts), and re-run the playbook, finally the obtained configurations are correct.

Hi @NierYYDS. 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.
