Update cluster-authentication-operator not to go degraded without console

This is a clone of issue OCPBUGS-3441. The following is the description of the original issue:
—
Update the cluster-authentication-operator to not go degraded when it can’t determine the console url.  This risks masking certain cases where we would want to raise an error to the admin, but the expectation is that this failure mode is rare.

Risk could be avoided by looking at ClusterVersion's enabledCapabilities to decide if missing Console was expected or not (unclear if the risk is high enough to be worth this amount of effort).

AC: Update the cluster-authentication-operator to not go degraded when console config CRD is missing and ClusterVersion config has Console in enabledCapabilities.
