> In GrpcLogAppender when an append entry times out we remove the entry from
> the pendingRequests. This decreases the size of pendingRequests which affects
> the logic in GrpcLogAppender#shouldWait. Further we also consider heartbeats
> in shouldWait because heartbeats are tracked in pendingRequests. It should
> actually wait on the number of log entries which are appended to follower but
> have not yet been processed by it.
> GrpcConfigKeys.Server.leaderOutstandingAppendsMax should also be a fraction
> of RaftServerConfigKeys.Log.queueSize. This brings flow control for leader's
> append entries to follower because then number of outstanding append entries
> in leader would be limited by maximum number of operations in raft log worker.
