Integrates audit functionality into CQL statement processing to enable tracking of database operations. Key changes: - Add audit_info and statement_category to all CQL statements - Implement audit categories for different statement types: - DDL: Schema altering statements (CREATE/ALTER/DROP) - DML: Data manipulation (INSERT/UPDATE/DELETE/TRUNCATE/USE) - DCL: Access control (GRANT/REVOKE/CREATE ROLE) - QUERY: SELECT statements - ADMIN: Service level operations - Add audit inspection points in query processing: - Before statement execution - After access checks - After statement completion - On execution failures - Add password sanitization for role management statements - Mask plaintext passwords in audit logs - Handle both direct password parameters and options maps - Preserve query structure while hiding sensitive data - Modify prepared statement lifecycle to carry audit context - Pass audit info during statement preparation - Track audit info through statement execution - Support batch statement auditing This change enables comprehensive auditing of CQL operations while ensuring sensitive data is properly masked in audit logs.
