This change list includes several fixes:
1. Adds a rule to push subplan into group-by
2. Adds a rule to eliminate subplan with input cardinality one
3. Fix the nested running aggregate runtime
4. Adds a wrapper of FrameTupleAppender to internally flush full frames.
   A TODO item is to cleanup existing usage of FrameTupleAppender to use the wrapper, which makes code simpler.
