> During bootstrap dump of ACID tables, let's consider the below sequence.
> - Current session (REPL DUMP), Open txn (Txn1) - Event-10
> - Another session (Session-2), Open txn (Txn2) - Event-11
> - Session-2 -> Insert data (T1.D1) to ACID table. - Event-12
> - Get lastReplId = last event ID logged. (Event-12)
> - Session-2 -> Commit Txn (Txn2) - Event-13
> - Dump ACID tables based on validTxnList based on Txn1. --> This step skips 
> all the data written by txns > Txn1. So, T1.D1 will be missing.
> - Commit Txn (Txn1)
> - REPL LOAD from bootstrap dump will skip T1.D1.
> - Incremental REPL DUMP will start from Event-13 and hence lose Txn2 which is 
> opened after Txn1. So, data T1.D1 will be lost for ever.
> Proposed to capture the lastReplId of bootstrap before opening current txn 
> (Txn1) and store it in Driver context and use it for dump.
