Add a temporary checkin for my current work on DISTINCT with GROUP BY
fix the distinct with AVG optimization, decide to adds DISTINCT at the top level of the plan to simplify all the work; Still need to optimize the EE to have the consistent order as the input for special GROUP BY without aggregations
Disable the DISTINCT push down optimizations; Add test cases first
Add code to have inserted order preserved HASH aggregations for certain interesting cases
remove the DISTINCT related plan node and executors, both EE and Java
