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().
