[Improvement] Adds the registerIcebergCatalogConfig abstract interface

[xunliu]

What would you like to be improved?

The IcebergREST has three impalement IT classes.
I think it better to add the registerIcebergCatalogConfig abstract interface in IcebergRESTServiceBaseIT.class.

How should we improve?

Use an abstract interface replace switch statement.

com/datastrato/gravitino/integration/test/catalog/lakehouse/iceberg/IcebergRESTServiceBaseIT.java

  private void registerIcebergCatalogConfig() {
    Map<String, String> icebergConfigs;

    switch (catalogType) {
      case HIVE:
        icebergConfigs = getIcebergHiveCatalogConfigs();
        break;
      case JDBC:
        icebergConfigs = getIcebergJdbcCatalogConfigs();
        break;
      case MEMORY:
        icebergConfigs = getIcebergMemoryCatalogConfigs();
        break;
      default:
        throw new RuntimeException("Not support Iceberg catalog type:" + catalogType);
    }

    AbstractIT.registerCustomConfigs(icebergConfigs);
    LOG.info("Iceberg REST service config registered," + StringUtils.join(icebergConfigs));
  }
