> KUDU-1563 adds support for INSERT_IGNORE, UPDATE_IGNORE, and DELETE_IGNORE.
> However, it is currently lack of per-session metrics about how many rows get ignored vs modified.
> In regular INSERT operation, we depends on per_row_errors field in WriteResponsePB to count how many row operations are failed.
> [https://github.com/apache/kudu/blob/0cb2b7c/src/kudu/tserver/tserver.proto#L175-L183] 
> But with INSERT_IGNORE, this field will be empty. We should add relevant metrics field to this WriteResponsePB.
