## What this PR does Removes the `apiServerEndpoint` fallback for `MASTER_NODES` in the `isp-full-generic` variant. When `MASTER_NODES` is not explicitly set (the default), the template used to parse a single IP from `apiServerEndpoint` and pass it to kube-ovn. This prevented kube-ovn from discovering all control-plane nodes, breaking OVN RAFT consensus on multi-master clusters (`ovn-central` crashed with `host ip X not in env NODE_IPS`). Now kube-ovn uses its built-in Helm `lookup` to find all control-plane nodes by the `MASTER_NODES_LABEL` (`node-role.kubernetes.io/control-plane=true`), correctly discovering all masters. Explicit `MASTER_NODES` override via platform values is preserved. The `isp-full` (Talos) variant is not affected — it uses a separate code path. Fixes #2242 ### Release note ```release-note [kube-ovn] Fix multi-master support for generic Kubernetes clusters by letting kube-ovn auto-discover control-plane nodes by label instead of falling back to a single API server IP ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Introduced support for automatic control plane node discovery using Kubernetes node labels, providing greater flexibility and scalability options for cluster configurations. * **Bug Fixes** * Removed unreliable automatic node configuration fallback logic to improve overall deployment consistency and predictability. Master nodes now require explicit configuration or automatic discovery through Kubernetes node labels. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
