[jira] [Created] (KUDU-3351) Add insert error count metrics in WriteResponsePB

Riza Suminto created KUDU-3351:
----------------------------------

             Summary: Add insert error count metrics in WriteResponsePB
                 Key: KUDU-3351
                 URL: https://issues.apache.org/jira/browse/KUDU-3351
             Project: Kudu
          Issue Type: Improvement
            Reporter: Riza Suminto


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.
