Multus + DHCP IPAM example

Prerequisites: Multus + NetworkAttachmentDefinition CRD installed.

In order to have DHCP working as an IPAM plugin -- you'll need to have the DHCP CNI binary running.

In this example, we'll run this (as a daemonset) from the dougbtv/dhcp image, which is based on Tomo's dockerfile.

About my setup: In this setup, I use a macvlan plugin as the secondary interface for Multus. In my setup, I used an upstream Kubernetes running on KVM guests. The master device for macvlan is eth0 and that device is connected to a bridge in the 192.168.122.0/24 network space, and has an already running DHCP server available.
