    Support Ironic interface attach/detach in nova virt

    In order to support different Ironic network drivers that may need to
    implement vif to pif mapping in different ways, we've added new APIs
    in Ironic to abstract this behaviour. This patch switches the Ironic
    virt driver over to use this API. As part of this change the virt driver
    will no longer provide the macs_for_instance function, as Ironic will
    handle updating the Neutron ports during the provisioning process.

    Update interface mac addresses in configdrive network_metadata with
    ironic node ports values.
