    Filter the ports by VNIC type

    In ``check_baremetal_ports_dhcp_options``, the ports need to be
    retrieved based on the VNIC type. The VNIC type is stored in
    "ml2_port_bindings" table, not "ports" table. Because the ML2Plugin
    ``get_ports`` method can filter only by "ports" database register
    fields, it is needed to retrieve those ports using a custom database
    query and then use the plugin method to retrieve the ports, converted
    to dictionaries and the extensions processed.
