Commit Message

Add NetlinkDeviceManager for declarative device lifecycle management

Introduce NetlinkDeviceManager, a controller that declaratively manages
Linux network device lifecycle with self-healing and dependency resolution.

Key features:
- Declarative API: Define desired device state (Bridge, VXLAN, VLAN, VRF, Dummy)
  and the manager ensures convergence
- Ownership tracking: Uses IFLA_IFALIAS to mark managed devices, preventing
  conflicts with external tools
- Dependency resolution: Automatically retries device creation when master/parent
  is not yet present
- Self-healing: Periodic reconciliation catches external drift and restores
  desired state
- Bridge VLAN/VNI mappings: Manages VID-to-VNI mappings for VXLAN devices
  with VniFilter enabled
- Bridge port settings: Configures vlan_tunnel, neigh_suppress, learning

Also extends NetLinkOps interface with:
- LinkModify for atomic attribute updates
- Bridge VLAN operations (BridgeVlanAdd/Del, BridgeVniAdd/Del, tunnel info)
- Bridge port settings (LinkSetVlanTunnel, LinkSetBrNeighSuppress, LinkSetLearning)
- Error checking helpers (IsEntryNotFoundError, IsAlreadyExistsError)
