Tracker for migrating lock contention flags to config in k8s upstream

[ipochi]

This issue mostly acts as a tracker for driving migrating the lock contention kubelet flags to a config file as we are using in Lokomotive.

Part of the work is done by an external person. This work is now upon us to get the feature merged.

1/3 PRs are merged, the effort centers around merging the remaining 2 existing PRs or closing them and opening new ones.

Associated PRs

kubernetes/kubernetes#97028
kubernetes/test-infra#20106
kubernetes/kubernetes#96775

Update:

• I created a PR Add e2e lock contention job kubernetes/test-infra#22758 to supersede Adding Kubelet E2E Lock Contention job kubernetes/test-infra#20106. I reached out to the author of the original PR and he was kind enough to close his PR in favor of mine.

kubernetes/test-infra#22758 was merged few days ago.

• I created another PR with the actual test in E2E test for kubelet exit-on-lock-contention kubernetes/kubernetes#103608 which was created to supersede Kubelet exit on lock contention E2E test kubernetes/kubernetes#96775

The new PR takes a different approach thereby making already merged PR (kubernetes/kubernetes#97028) not needed for this feature.

I have provided more details on kubernetes/kubernetes#103608 and created a follow up PR kubernetes/test-infra#22758. If agreed that kubernetes/kubernetes#97028 is not needed then I will create another PR reverting the said change.
