The test for checking container restarts in a Pod with restartable-init-1
and regular-1 is flaky. Right now, when we check if restartable-init-1 has
restarted, we see if it hasn’t written the "Started" log after regular-1 has
written its "Started" log.
But even though the startup sequence starts with restartable-init-1 and then
regular-1, there’s no guarantee they’ll finish starting up in that order.
Sometimes regular-1 finishes first and writes its "Started" log before restartable-init-1.
1. restartable-init-1 Starting
2. regular-1 Starting
3. regular-1 Started
4. restartable-init-1 Started
In this test, the startup order doesn’t really matter; all we need to check is
if restartable-init-1 restarted. So I changed the test to simply look for
more than one "Starting" log in restartable-init-1's logs.
There were other places that used the same helper function DoesntStartAfter,
so replaced those as well and deleted the helper function.
with systemd cgroup driver and cpumanager none policy.
This was originally planned to be a correctness check for
https://issues.k8s.io/125923, but it was difficult to reproduce the bug,
so it's now a regression test against it.

when nodes removes the label that satisfies the pod affinity, the running pods are not affected, but restarting the kubelet will kill these pods.
