Review comment:
Add more tests for the following scenarios.
1. REPL LOAD fails after replicating table or partition objects with stats
but before setting last replId. Now, retry which takes alter table/partition
replace flows and stats should be valid after successful replication. Need this
for all non-transactional, transactional and migration cases.
2. Parallel inserts with autogather enabled. Now, we will have events such
that multiple txns open when updating stats event. Also, try to simulate that
one stats update was successful and the other one invalidates it due to
concurrent writes.
