use register_cli_opts instead of register_opt for multiple options

[Kanagaraj Manickam]

In heat/bin/heat-keystone-setup-domain, register_opt is used to register many opts while olso provides an api already for the same. so this defect is filed to use the correct api.

Remove the following lines
for opt in opts:
    cfg.CONF.register_opt(opt, cli=True)

And

Add this line
cfg.CONF.register_cli_opt(opts)
