Description

In order to support DDL computed column for a connector, we should

• Add supported key as "schema.#.expr"
• Fix the TableSource#getReturnType and TableSource#getProducedDataType if it use the virtual columns as part of its schema
• Fix the format schema if the schema is derived from the TableSchema and the TableSchema contains virtual columns.
