Feature Control list gives an option to assign specific tools and features of Administration & Data Server and the Configuration Manager to the users. But I am not looking for that.
It is a sort of multi tenant configuration, sharing the same resources/instances of contact center setup. I will have multiple Line of Business created in the system and users, reporting, etc are segregated.
The above mentioned scenario is possible using ICMDBA's Partitioning (Logger Database) and Business Entity configuration.
I do not know why Cisco has removed this feature from 8.x onwards.
