> Add new EVENT_COMMIT_TXN to log the metadata/data of all tables/partitions 
> modified within the txn.
> *Source warehouse:*
>  - Create EVENT_COMMIT_TXN event type with corresponding message format etc.
> *Target warehouse:*
>  - Repl load should read this event from the dump.
>  - Validate the source txn ID from the event using the Source-Target Txn ID 
> map maintained in target metastore. Also, need to check if corresponding 
> target txn ID is valid.
>  - If valid, then apply the event and commit the corresponding target 
> transaction.
>  - This new event should be idempotent such that if it is applied twice, then 
> second time it should be loop.
