What this PR does / why we need it:

This PR stops the kubelet service if running, stops running containers, and then stops the crio service before changing the runtime (e.g., runc to crun). After making the changes, it starts the crio and kubelet services.

Which issue(s) this PR fixes:

Fixes #11907

Special notes for your reviewer:

Kubernetes has changed the default runtime for CRI-O from runc to crun starting with version 1.31. This change has caused upgrade failures because CRI-O cannot handle a real-time runtime switch. As mentioned in cri-o/cri-o#8705 (comment), when switching runtimes, we need to ensure that the kubelet service and running containers are stopped before making the change.

Hi @mahendra77024. 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.
