> API Server has /ws/v1/services/{service_name}.  This REST end point returns Services object which contains both configuration and status.  When status or macro based parameters changed in Services object, it can confuse UI code to making configuration changes.  The suggestion is to preserve a copy of configuration object independent of status object.  This gives UI ability to change services configuration and update configuration.
> Similar to Ambari, it might provide better information if we have the following separated REST end points:
> {code}
>  /ws/v1/services/[service_name]/spec
>  /ws/v1/services/[service_name]/status
> {code}
