OCPBUGS-111601: Prevent conversion webhook startup deadlock

[bryan-cox]

What this PR does / why we need it:

Prevents the HyperShift operator from deadlocking during startup when CAPI resources are stored as v1beta2 but operator caches request v1beta1 resources.

Failure evidence

• Failed Azure self-managed run 2091848958857973760
• Original operator container log
• Original operator previous-container log

The management HostedCluster was created but never received status and timed out waiting to become available. Every operator container repeatedly failed to synchronize the v1beta1 MachineSet and MachineDeployment informers:

conversion webhook for cluster.x-k8s.io/v1beta2, Kind=MachineSet failed:
Post "https://operator.hypershift.svc:443/convert?timeout=30s":
no endpoints available for service "operator"

The operator's webhook server was listening locally on port 9443, but the Service excluded the pods because they were not Ready. The existing readiness and liveness probes scraped /metrics. The NodePool metrics collector synchronously lists v1beta1 MachineSets and MachineDeployments through the controller-runtime cache with a background context. Those requests block until the same informers synchronize, so /metrics cannot complete while conversion is unavailable.

This creates a loop:

1. Cache synchronization requires v1beta2-to-v1beta1 conversion.
2. Conversion requires a ready operator Service endpoint.
3. Readiness probes /metrics.
4. /metrics waits for cache synchronization.
5. Liveness eventually restarts the container and repeats the cycle.

The captured containers restarted after approximately five and a half minutes, matching the configured liveness timing. A healthy post-migration periodic had ready operator endpoints and no conversion errors, demonstrating that normal v1beta1 reads work once the webhook is reachable. The failure is specifically the zero-ready-endpoint startup case, not conversion functionality in a healthy deployment.

Fix

• Serve liveness and readiness from controller-runtime's dedicated health server instead of /metrics.
• Keep liveness independent of caches with healthz.Ping.
• When webhooks are enabled, report Ready only after the local TLS webhook listener is reachable using WebhookServer.StartedChecker().
• Preserve simple ping readiness for local runs where webhooks are disabled.

This allows the pod to become a Service endpoint before cache synchronization, which lets conversion complete and the controllers start.

This is separate from #9384. That PR fixes the independently reproduced v2 upgrade-test rollout race; this PR fixes management-cluster creation failures where the operator cannot start.

📝 Walkthrough

Walkthrough

The HyperShift operator now exposes health checks on port 8081. Its deployment uses /healthz for liveness and /readyz for readiness. The operator registers a ping health check and, when webhooks are enabled, uses webhook server startup state for readiness. Tests validate deployment probe configuration and both webhook-enabled and webhook-disabled readiness behavior.
