> 1. ServiceConfig API call uses "MpackName-Vesion" for SG instead of just
> "MpackName".
> - With "[AMBARI-23269] Removed mpack version from service group name (#692)"
> we have started using just the *Mpack* Name to create the SG.
> - But we haven't updated the Service Configs API POST calls, which still
> continue to use *MpackName-Vesion* for referring SG. This needs to be updated.
> Failure :
> POST

> NPE is because *recoveryConfigHelper* is not initialized. Further,
> *hostLevelParamsHolder* and *topologyHolder* are also null.
