> ServiceGroup was a new sub-resource added for cluster in AMBARI-21594.
> This Task involves :
> - moving *Services* which was earlier a sub-resource of *Cluster* under *ServiceGroup*
now, and
> -  using *Servicegroup* while doing Creation, Update and retrieval of *HostComponents*
and *ServiceComponents*.
> -  UI changes which includes creating a *default ServiceGroup named 'core'*, and all
services created goes under it. Further, making UI calls SG aware, while making a call.
> The new API calls will be the following:
