      During periods of apiserver unavailability, the cluster-etcd-operator may have reported errors such as "namespace openshift-etcd not found", even when the namespace exists. A caching issue has been resolved that indicated to the controllers that no namespace existed at all.

      This is a clone of issue OCPBUGS-44570. The following is the description of the original issue:
      —
      Description of problem:

      When apiserver is not available briefly, the CEO status suggests that the openshift-etcd namespace does not exist:

> EtcdEndpointsDegraded: EtcdEndpointsController can't evaluate whether quorum is safe: CheckSafeToScaleCluster failed to get bootstrap scaling strategy: failed to get openshift-etcd namespace: namespace "openshift-etcd" not found...

which is evidently wrong, because the api has just responded with that exact status, which means etcd has returned this as a result.    

We should reword this message to indicate the actual error.

Code path is here:
https://github.com/openshift/cluster-etcd-operator/blob/release-4.17/pkg/operator/ceohelpers/bootstrap.go#L120-L123

      Version-Release number of selected component (if applicable):

      any supported release

      How reproducible:

      always

      Steps to Reproduce:

          1. created some temporary downtime on apiserver
    2. check the CEO status using oc get co

      Actual results:

      CEO returns "failed to get openshift-etcd namespace: namespace "openshift-etcd" not found."

      Expected results:

      CEO should not indicate that namespace is missing
