[apache#2962] feat(catalog-lakehouse-iceberg): Add reserved propertie…
…s to Iceberg Table Properties in Gravitino (apache#3511) ### What changes were proposed in this pull request? Add reserved properties to Table properties when load an Iceberg table, such as: ``` provider, format, current-snapshot-id, location, format-version, sort-order, identifier-fields ``` ### Why are the changes needed? for example, when execute `desc extended IcebergTableName`，it will get some information from the result properties of this Iceberg table, so it should contain the above properties. Fix: apache#2962 ### Does this PR introduce any user-facing change? No. ### How was this patch tested? New UTs and ITs.
