    Fix nova-serialproxy when registering cli options
    
    In latest devstack, nova-serialproxy fails to start because it crashed
    when it tries to register the cli options.
    
    The issue is that it tried to register an array of options by invoking
    conf.register_cli_opt(), when multiple options need to be register
    through conf.register_cli_opts().
