[client] KUDU-3351: Add ResourceMetricsPB into WriteResponsePB
KUDU-1563 adds support for INSERT_IGNORE, UPDATE_IGNORE, and
DELETE_IGNORE. However, it was lacking the per-session metrics about how
many rows get ignored vs modified. This patch implements the per-session
metrics by introducing a new ResourceMetricsPB field into the
WriteResponsePB that's populated in every response sent back to the
client.

> The Java client currently has an [option to ignore duplicate row key errors|
> https://kudu.apache.org/apidocs/org/kududb/client/AsyncKuduSession.html#setIgnoreAllDuplicateRows-boolean-],
> which is implemented by filtering the errors on the client side. If we are
> going to continue to support this feature (and the consensus seems to be that
> we probably should), we should promote it to a first class operation type
> that is handled on the server side. This would have a modest perf.
> improvement since less errors are returned, and it would allow INSERT IGNORE
> ops to be mixed in the same batch as other INSERT, DELETE, UPSERT, etc. ops.
