Append to a batch transactionally

[yujiarista]

Currently if I append a row with bad data to a batch, the batch is basically ruined.
Can we add a transactional semantic to Batch.Append so no data is appended to any column if there is an error?

I think it can be resolved by following the template below

func append() (err error) {
   batch := conn.PrepareBatch(...)
   defer func() {
     if err != nil {
        err = batch.Abort()
        return
     }
     err = batch.Send()
   }
   .....
}

Maybe you have a different case where template above doesn't work

My suggestion is basically the same as #1223. Closing this one.
