Description of problem:
In CI we occasionally see connection refused when connecting through the NLB to the kube-apiserver. With /readyz used as NLB target health check and our timing (35 sec kube-apiserver minimum-termination-period, 3*10 sec NLN target unhealthz threshold) this should never happen.
Version-Release number of selected component (if applicable):
Randomly in CI.
