### Search before asking
- [X] I have searched in the [issues](https://github.com/apache/incubator-uniffle/issues?q=is%3Aissue) and found no similar issues.
### Describe the feature
There are two sub-clusters e.g. A and B are federated by YARN Federation and only when a MR is routed to sub-cluster B should RSS be enabled. Thus a new way to enable MR RSS like spark `DelegationShuffleManager` is desired, we hope this feature could be supported.

Research direction
The issue names no files, tests, or entry points, so first map how MapReduce requests are routed across YARN Federation sub-clusters and where RSS is enabled. Clarify the intended configuration and routing behavior; done means RSS is enabled for jobs routed to sub-cluster B while remaining disabled for jobs routed to sub-cluster A, with coverage for both paths.
