    Check port VNIC type when associating a floating IP

    When associating a floating IP to a port and the router is distributed,
    the VNIC type of this port must be "normal" only. In any other case,
    the floating IP can't be assigned. For example, a SR-IOV can have a
    floating IP if the router is distributed (the router is in the same
    host of the port).

    This patch adds also function can_port_be_bound_to_virtual_bridge to
    neutron/db/l3_db.py module.
    Originally this function was introduced in neutron-lib with [1] but
    in stable branch there is older neutron-lib used so this isn't available
    from neutron-lib.
