Support Min/Max aggregation for partitioned stats (i.e. First/Last message timestamps)

[Hor911]

When we agggregate partitioned statistics (from different parts, i.e. when single shards send data through several read actors) we should support different aggregations functions, i.e.:

• FirstMessageMs should be aggregated by MIN
• LastMessageMs should be aggregated by MAX

Before this change, all aggregations were processed with SUM and result incorrect statistics

P.S. Also minor fix to assign HistorySampleCount and restore time series recordings is included
