Once T311739: [Iceberg] Update Refine Sanitize to insert into Iceberg tables is done and working, we will need to replace the event_sanitized database with the iceberg version:

• Announce to users
• Have users do some testing in event_sanitized_iceberg, including testing with superset

Migration:

• Rename event_sanitized to event_sanitized_hive, rename event_sanitized_iceberg to event_sanitized
• Modify superset dashboards to use timestamp based (instead of partition based) queries.
• Eventually: delete event_sanitized_hive database
