The only reason for importing nova.config now is where one of the options defined in that file is needed. Rather than importing nova.config using an import statement, use CONF.import_opt() so that it is clear which option we actually require. In future, we will move many options out of nova.config so many of these import_opt() calls will either go away or cause a module other than nova.config to be imported.
