描述

Add streaming APIs (RpcClient, RpcServer), implement it based on gRPC.

This is a subtask that belongs to the first step of #672 In this subtask, we need a streaming impl, for the leader (client) to continuously send raft logs to followers.

Main goals:

  • Add streaming API to RpcClient and RpcServer
  • Implement streaming based on gRPC (We are not going to use bolt to implement)

研究方向
Study the existing RpcClient and RpcServer interfaces (jraft core/src/main/java/com/alipay/sofa/jraft/rpc/). Based on gRPC streaming, design and implement streaming versions. Refer to subtask #672 for context. The implementation should allow leader to continuously send raft logs to followers. Consider using gRPC's bidirectional streaming.
