    Convert port to str when validate console port

    The port type must be str type in nova-serialproxy side as we convert to str
    forcefully before rpc validate_console to compute service[1]. But on the
    compute side, the driver may be return int type like ironic serial console[2].
    So the validate_console_port may always return False as type inconsistence[3].
