Rong Ou	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.	2022-05-05 21:49:22 +08:00
