Code Review
This pull request introduces documentation for logging session connection attributes to the slow query log, including new system and status variables such as performance_schema_session_connect_attrs_size. Critical issues were identified where Git conflict markers were left in the SLOW_QUERY and CLUSTER_SLOW_QUERY table schemas, which must be resolved. Additionally, several sections require updates to use active voice and the second person to comply with the documentation style guide.

This file contains Git conflict markers (e.g., <<<<<<< HEAD, =======, >>>>>>>) inside the SQL code blocks. These markers indicate a failed merge or cherry-pick and must be resolved before the documentation can be published. Please remove the markers and the redundant old table schema, keeping only the updated version.

Similar to the SLOW_QUERY table above, the CLUSTER_SLOW_QUERY section also contains Git conflict markers that need to be resolved. Ensure that only the correct, updated table schema is displayed in the final output.
