Improve DDL handling with OpenLogReplicator

Currently, OpenLogReplicator has very strict guidelines about what DDL events are consumed, namely:

• Skips any DDL with no schema or where the table starts with "OBJ_"
• Skips any DDL where table starts with "BIN$" or ends with "==$0"
• Skips any DDL that isn't CREATE|ALTER|DROP|TRUNCATE TABLE
• Skips DDL with RENAME CONSTRAINT
• Skips DDL with RENAME TO BIN$...

Ideally we shouldn't skip any of these scenarios unless explicitly necessary such as use cases where the table name is unknown ("OBJ_" prefix) or where the table has been moved to the recycle bin and is now known with a name starting with "BIN$"/
