Description: Description of problem:
 {code:none}
 While working on making IPsec upgrade as a mandatory jobs for OCP releases with PR: https://github.com/openshift/release/pull/63528, KubeAPIErrorBudgetBurn alert is seen for the 4.17 and 4.16 rehearsal jobs. Looks like this is seen sporadically.

We have many guards making sure that there are always at least two instances of the kube-apiserver. If we ever reach a single kube-apiserver and it causes disruption for the clients, other alerts such as KubeAPIErrorBudgetBurn will fire.
KubeAPIDown is here to make sure that Prometheus and really any client can reach the kube-apiserver, which they can even when there is only one instance of kube-apiserver running. If they can't or that availability is disrupted, `KubeAPIErrorBudgetBurn` will fire.
