Bootstrapping of ACID tables, need special handling to replicate a stable state of data.
 - If ACID feature enables, then perform bootstrap dump for ACID tables with in read txn.
-> Dump table/partition metadata.
-> Get the list of valid data files for a table using same logic as read txn do.
-> Dump latest valid table Write ID as per current read txn.
 - Find the valid last replication state such that it points to event ID of open_txn event of oldest on-going txn.
