Add documentation for the new useInterfaceNetwork configuration parameter introduced in containernetworking/plugins#1257.

This option instructs the host-device plugin to capture the host interface's IP addresses and routes and apply them inside the container, which is critical for cloud/virtual environments where L3 configuration is provisioned directly on the host device.

The update includes:

  • Parameter description with type, default, and behavior details
  • Note about host interface persistence requirements on DEL
  • Two example configurations (standalone and combined with IPAM)
