Description

Primary copies of partitions don't contain entry duplicates.
Because, entries can be filtered based on version on the creation time.

So, during iteration we don't need to track possible duplicates inside DumpedPartitionIterator implementation in partKeys variable. This will decrease memory consumption and improve performance of dump iteration and therefore dump check procedures.
