## 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.
2.1. For count function, the implementation is as
follows：distinct_multi_count(update)+ distinct_multi_count(merge)+sum(update)+
sum(merge)
