    Expose node's network_interface field in API

    This patch exposes the node's network_interface field in the REST API.
    It also adds restrictions on the node states in which network
    interface change is possible and whether the requested network
    interface is enabled.

    As a temporary solution until the driver composition work is completed,
    we have taken an approach that requires all API and Conductor nodes to
    have the same setting for enabled_network_interfaces. There are inline
    notes in the code indicating where we will address this in the future.
