[CARBONDATA-197]Changed List To Queue for storing block execution infos
Problem: we are maintaining block execution infos for each block in a list
and in detail query executor we are removing it for execution. If number of
infos in list is more than removal will be time taking operation as we are
removing from to top index and it will sink every time.
Solution:Queue will be proper data structure for this scenario
