- Set by default SWIFT_REPLICAS to 1 since this is the most common use case when using it in devstack. - If we have swift_replicas to 1 launch the object container account and proxy servers in foreground in screen. - Allow any s- services if we have just 'swift' in service enabled instead of having to specify all s- services to enable swift. This will be removed in the future. Change-Id: I496f79e14f99bd7e9f2c7deee12a4b6e935c3a5b
