The current patch depends on YARN-7202 changes.

>                 URL: https://issues.apache.org/jira/browse/YARN-7216
>             Project: Hadoop YARN
>          Issue Type: Sub-task
>          Components: api, applications
>            Reporter: Eric Yang

> 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}
