Paweł Zakrzewski 98f5e49ea8 audit: Add support to CQL statements
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.
