### Describe the bug

KyuubiStatement.execute always return true even it's running a CREATE TABLE command in Spark SQL engine which doesn't return any results

`true if the first result is a ResultSet object; false if it is an update count or there are no results`
`boolean execute(String sql) throws SQLException;`

### Are you willing to submit PR?

- [ ] Yes I am willing to submit a PR!

Start at the KyuubiStatement.execute entry point and trace how CREATE TABLE commands from the Spark SQL engine determine their result. Confirm the JDBC contract for statements with no ResultSet, then add or update coverage so execute returns false for that case.
