14ef38b834 Initial support for federated learning (#7831) 
Federated learning plugin for xgboost:
* A gRPC server to aggregate MPI-style requests (allgather, allreduce, broadcast) from federated workers.
* A Rabit engine for the federated environment.
* Integration test to simulate federated learning.

Additional followups are needed to address GPU support, better security, and privacy, etc.
