Migrate iceberg between different data center:
For version 1 table: you can just load the data files into Spark dataset
and then write into target table.
For version 2 table: config different cluster Spark catalog like this:
```
.config("spark.sql.catalog.hive_prod_src", classOf[SparkCatalog].getName)
.config("spark.sql.catalog.hive_prod_src.type", "hive")
.config("spark.sql.catalog.hive_prod_src.uri", $hiveMetaStores1)
.config("spark.sql.catalog.hive_prod_dst", classOf[SparkCatalog].getName)
.config("spark.sql.catalog.hive_prod_dst.type", "hive")
.config("spark.sql.catalog.hive_prod_dst.uri", $hiveMetaStores2)
```
read and write iceberg data by Spark SQL.
