*More detailed description of your change* It's not very convenient to return Long for `RaftClient.scheduleAppend`, in this PR we add a `RaftAppendResult` class to replace it. I also found that we lack logic on append failure, for example, the `ControllerWriteEvent` won't check the result of `raftClient.scheduleAppend`, this should be fixed in a future PR. *Summary of testing strategy (including rationale)* QA -- This is an automated message from the Apache Git Service.
