Change subject: IMPALA-7970 : Add support for automatic invalidates by polling metastore events ...................................................................... IMPALA-7970 : Add support for automatic invalidates by polling metastore events This change adds support to CatalogD to poll metastore events to issue invalidate on tables automatically. It adds basic infrastructure to poll HMS notifications events at a configurable frequency using a backend config called hms_event_polling_frequency_s flag. Currently, it issues invalidate at tables when it received alter events on table and partitions. It also adds tables/databases and removes tables from catalogD when it receives create_table/create_database and drop_table/drop_database events. The default value of hms_event_polling_frequency_s is 0 which disables the feature. A non-zero value in seconds of this configuration can be used to enable the feature and set the polling frequency. The change also adds a new test class to test the basic functionality for each of the event type which is supported.
