> Currently {{TableEnvironment}} manages a list of registered external catalogs as well
as in-memory meta objects, and interacts with Calcite schema. It would be cleaner to delegate
all those responsibilities to a dedicate class, especially when Flink's meta objects are also
stored in a catalog.
> {{CatalogManager}} is responsible to manage all meta objects, including external catalogs,
temporary meta objects, and Calcite schema.
