OCPBUGS-29894: Check if CRLs are downloaded when determining ready status

[rfredette]

Require all CRLs to be downloaded before the router can report that it's ready. This prevents forwarding requests to a router until it's ready to handle mTLS.

This fixes OCPBUGS-29894

This makes a router pod start failing readiness checks if it has outdated CRLs, right?

To fix OCPBUGS-29894, it should be sufficient to fail readiness only for the initial synch, so that startup probes (which use the readiness endpoint) fail until the initial synch is done.

Once the router pod has done the initial synch, we want readiness checks to pass even if refresh fails, for two reasons:

• The expectation is to restore the behavior prior to openshift/cluster-ingress-operator#939 and #472, and that behavior was to prevent a router pod from serving traffic until it had CRLs, not to prevent a router pod from serving traffic if it had outdated CRLs.
• It is generally less bad to continue using outdated CRLs, rather than to stop serving traffic entirely when refresh fails.

This does make me realize that we need a Prometheus metric and an alert when refresh fails for a prolonged period. Failure to refresh has two nasty implications:

• Router pods are using outdated CRLs.
• The next rolling update of the router deployment (for an upgrade, configuration change, or whatever reason) could get stuck as presumably the new pods would fail on initial synch.

Ack, I'll update this so that the CRLs readiness check is only used for the initial sync.

This does make me realize that we need a Prometheus metric and an alert when refresh fails for a prolonged period.

That make sense, although I think that's out of the scope of this bug. I'll open a jira issue for that.
