Allow users to select whether DROP events should be processed

[ddcprg]

As a Shunting Yard user
I'd like to choose whether drop table and drop partition events should be processed in the replica metastore
So I can decide whether my replica is going to be a mirror of the original metastore or the can be unsycned

Overview

Some users may decide to keep their replica tables partially synced. This could be particularly useful for testing environments.

Acceptance Criteria

For each execution context provide the option to ignore DROP TABLE and DROP PARTITION events.
