pkg/monitortests/clusterversionoperator/legacycvomonitortests: Expand authentication reason exceptions

To cover the main hits in:

  $ curl -s 'https://search.ci.openshift.org/search?maxAge=48h&type=junit&name=4.15.*upgrade&context=0&search=clusteroperator/authentication.*condition/Available.*status/False' | jq -r 'to_entries[].value | to_entries[].value[].context[]' | sed 's|.*clusteroperator/\([^ ]*\) condition/Available reason/\([^ ]*\) status/False.*|\1 \2|' | sort | uniq -c | sort -n
        1 authentication APIServerDeployment_PreconditionNotFulfilled
        6 authentication OAuthServerDeployment_NoDeployment
        8 authentication APIServerDeployment_NoDeployment
       10 authentication APIServerDeployment_NoPod
       11 authentication WellKnown_NotReady
       36 authentication OAuthServerRouteEndpointAccessibleController_EndpointUnavailable
       43 authentication APIServices_PreconditionNotReady
       66 authentication OAuthServerServiceEndpointAccessibleController_EndpointUnavailable
       95 authentication APIServices_Error

I've also expanded the scope of [1] to match, but I have no problem if
folks decide to fork that bug into multiple trackers and have specific
exceptions for each tracker.
