openshift-sdn does not allow to configure a custom mac

openshift-sdn does not allow to configure a custom mac.

I am copying here @booxter thorough explanation for the similar issue on ovn-kubernetes:

OK, let me expand because it sounds like perhaps Alon asked the project to come up with its own solution for hardware addresses, while in reality there is prior art in CNI plugins for the same.

The Network Plumbing working group of Kubernetes came up with a standard for network attachment definitions: https://docs.google.com/document/d/1Ny03h6IDVy_e_vmElOqR7UdTPAG_RNydhVE1Kx54kFQ/edit

This document explains how additional networks can be attached to pods and is implemented by Multus CNI plugin. This document defines, among other things, the mac attribute that can be passed via CNI_ARGS into the plugin. If it's passed, then the plugin is supposed to enforce it for the prepared binding. This feature is already implemented in multiple CNI plugins (e.g. ovs-cni, sriov-cni), it can also be implemented not natively via tuning plugin chaining. Other projects like KubeVirt / kubemacpool rely on this attribute for some features to work.

It would be very helpful if OVN-Kubernetes plugin adds support for this attribute like other plugins did, so that we can use it in KubeVirt / kubemacpool environments.

Thank you for consideration.
