   Currently, partition related ops like `Alter table add partition` and `Show partitions` fail due to Hive doesn't think an Iceberg table is partitioned even though it is, since the table partition metadata is in file sytem, NOT in HMS. We may resolved the issue in Spark 3.1.
   Spark 3.1 introduces interface SupportsPartitionManagement. We can let SparkTable extends it so that partition related ops can be supported for Iceberg table.
