Investigate missing insert table event for an insert operation on Iceberg table

Currently, we are not firing an insert table event to metastore when there is an insert operation on an Iceberg table. As a result, other impala clusters consuming the events from metastore are unaware of that insert operation resulting in (meta)data sync issues.

Need to investigate why the insert table event is not fired to metastore for an insert table operation on Iceberg table.
