[CARBONDATA-4320] Fix clean files removing wrong delta files Why is this PR needed? In the case where there are multiple delete delta files in a partition in a partition table, some delta files were being ignored and deleted, thus changing the value during the query What changes were proposed in this PR? Fixed the logic which checks which delta file to delete. Now checking the deltaStartTime and comparing it with deltaEndTime to check consider all the delta files during clean files. Does this PR introduce any user interface change? No Is any new testcase added? Yes, one test case has been added. This closes #4246
