Information schema for engine user query history

The system table information_schema.engine_user_query_history is a view, which is a virtual table based on ENGINE_QUERY_HISTORY. It applies filters to only show queries that were made by actual users.

Queries generated by the system, such as those from connectors, drivers, or SDKs, are marked with the boolean HTTP header Firebolt-Machine-Query. These system queries can include actions such UI page loads or query progress updates. These queries do not appear in information_schema.engine_user_query_history, but are available in ENGINE_QUERY_HISTORY, which acts as a complete audit log.
