sriov-network-metrics-exporter Infiniband support

What would you like to be added:
Prometeus-like exporter for virtualized SR-IOV Infiniband devices

Why is this needed:
The main priority of network operator is functionality for configuring/maintenance of Infiniband interfaces in k8s ecosystem.
Mellanox network-operator includes k8snetworkplumbingwg components to provide this or that functionality. One of k8snetworkplumbingwg components is sriov-network-metrics-exporter which can provide prometheus-like metrics for virtualized SR-IOV devices. However, in seems that maintainers of that project doesn't have resources to add support of Infiniband devices to their product.

At the very least, it makes sense that if we're setting up an infiniband, we want to get metrics from it. Right now, we can only get metrics from Ethernet. And I guess it won't take much effort from you.

Thanks in advance
