Description of problem:
Seen in 4.15 update CI:
: [bz-openshift-apiserver] clusteroperator/openshift-apiserver should not change condition/Available expand_less
Run #0: Failed expand_less 1h28m25s
{ 1 unexpected clusteroperator state transitions during e2e test run
Nov 22 21:47:32.876 - 1s E clusteroperator/openshift-apiserver condition/Available reason/APIServices_Error status/False APIServicesAvailable: rpc error: code = Unknown desc = malformed header: missing HTTP content-type}
While the Kube API server, if that's what's missing the header, is supposed to always be available, an issue that only persists for 1s is not long enough to warrant immediate admin intervention. Teaching the openshift-apiserver operator to stay Available=True for this kind of brief hiccup, while still going Available=False for issues where least part of the component is non-functional, and that the condition requires immediate administrator intervention would make it easier for admins and SREs operating clusters to identify when intervention was required.

The impact rates are low enough that I haven't checked older 4.y. And it's possible that some of those matches have the operator going Available=False for other reasons besides APIServices_Error:

How reproducible:
12% impact for periodic-ci-openshift-release-master-ci-4.15-e2e-azure-ovn-upgrade looks like the highest impact among the jobs with double-digit run counts.
Steps to Reproduce:
Run periodic-ci-openshift-release-master-ci-4.15-e2e-azure-ovn-upgrade a bunch of times watching the openshift-apiserver ClusterOperator's Available condition.
Actual results:
Some very brief blips of Available=False that self-resolve before an admin could possibly resolve to the summons.
Expected results:
No quickly-resolving blips in CI. No long runs of Available=False for issues that don't seem worth summoning an admin. Still going Available=False for outages that need immediate admin response.
