 Description   

We are using run() to execute the INSERT query for query stats which generates a warning on mysql_use_result() because there is no result set.

| Warning | 9999 | Columnstore Query Stats - fatal error running mysql_use_result() or empty result set in libmysql_client lib (-1) (unknown) |

We should have a flag in this function to state that we aren't expecting there to be results.

Set to minor because it means the write succeeded, just annoying that there is a warning.

This warning existed ever since queryStats was implemented. It was treated as a side effect. It is great to see this issue corrected.
