Issue:
Added support for baremetal virutal interfaces
See https://github.com/gophercloud/gophercloud/issues/1429

Adding virtual interfaces which is documented here: https://docs.openstack.org/api-ref/baremetal/#vifs-virtual-interfaces-of-nodes

This will be done similarly to https://github.com/gophercloud/gophercloud/pull/2722
