## Problem summary

The AggregateDisassemble rule is refactored and split into two rules, which are not dependent on each other.
1. AggregateDisassemble splits the agg into two phases: Local, Global.
1.1. For count function, the implementation is as follows:distinct_multi_count(update)+ distinct_multi_count(merge)

2. DistinctAggregateDisassemble splits the agg into 4 stages: Local, Global, Distinct Local, Distinct GLobal.
