Subject: [PATCH] feat: add node affinity for DaemonSet scheduling

- Implement node affinity to prevent scheduling on vkvm-us2
- Update affinity section in daemonset.yaml
- Ensure that the DaemonSet runs only on specific nodes

This change introduces a node affinity rule to the DaemonSet configuration,
allowing it to avoid scheduling on nodes labeled with `kubernetes.io/hostname`
set to `vkvm-us2`. This helps to ensure resource allocation and performance
by restricting the DaemonSet to the desired nodes.
