Description

We just supported HadoopTable api to create Iceberg table in Impala now, it's apparently not enough, so we preparing to support HadoopCatalog. The main design is to add a new table property named 'iceberg.catalog', and default value is 'hadoop.tables', we implement 'hadoop.catalog' to supported HadoopCatalog api. We may even support 'hive.catalog' in the future.
