📝 Walkthrough

Walkthrough

This change adds a new Kubernetes patch file to configure KServe's LLM scheduler component with TLS certificate handling settings. The kustomization.yaml is updated to reference the new patch, and a new patch file config-scheduler-patch.yaml defines an LLMInferenceServiceConfig that enables the certificates.kserve.io/expiration-v2 annotation on the scheduler to preserve TLS certificate expiration behavior during restarts.
