[jira] [Created] (FLINK-10698) Create CatalogManager class manages all external catalogs and temporary meta objects

-----------------------------------

             Summary: Create CatalogManager class manages all external catalogs and temporary meta objects
                 Key: FLINK-10698
                 URL: https://issues.apache.org/jira/browse/FLINK-10698
             Project: Flink
          Issue Type: Sub-task
          Components: Table API &amp; SQL
    Affects Versions: 1.6.1
            Reporter: Xuefu Zhang


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.
