Currently, REPAIR_GET_COMBINED_ROW_HASH RPC verb returns only the repair_hash object. In the future, we will use set reconciliation algorithm to decode the full row hashes in working row buf. It is useful to return the number of rows inside working row buf in addition to the combined row hashes to make sure the decode is successful. It is also better to use a wrapper class for the verb response so we can extend the return values later more easily with IDL.
