> Send Tephra family delete markers instead of real delete family markers to bypass the
Tephra coprocessor preDelete hook that writes the Tephra family delete marker immediately.
This ensures that the preBatchMutate hook sees the previous state correctly and prevents a
second unnecessary call to the Phoenix preBatchMutate hook.
> In addition, removing unnecessary call to generateDeletes for new data table rows.
