Struct AppendEntriesRequest 

pub struct AppendEntriesRequest {
    pub term: Term,
    pub leader_id: NodeId,
    pub prev_log_index: LogIndex,
    pub prev_log_term: Term,

    pub leader_commit: LogIndex,
}

AppendEntries RPC request

entries: Vec<LogEntry>

Log entries to store (empty for heartbeat)

leader_commit: LogIndex

Leader’s commitIndex
