1. Add support for pushing the filter on following fields into
InfoSchemaRecordGenerator:
- CATALOG_NAME
- COLUMN_NAME
2. Pushdown LIKE with ESCAPE. Add test
TestInfoSchemaFilterPushDown#testFilterPushdown_LikeWithEscape
3. Add a method visitCatalog() to InfoSchemaRecordGenerator to decide
whether to explore the catalog or not
4. Refactor CATALOG_DESCRIPTION and CATALOG_CONNECT as constant strings in
InfoSchemaConstants.java
5. Update TestInfoSchemaFilterPushDown#testPartialFilterPushDownWithProject
as
we are now pushing the filter on COLUMN_NAME field
