Title: rafthttp: set bigger value for MsgAppResp batch number

It is set a little bigger to avoid reaching maximal serving when using
streaming in good path.

Based on the log, it exceeds the maximal serving number of 8 messages at most. Considering our current send buffer size is 16, batch 1.5x more messages is enough for us to handle it.

fixes #1787
