[CARBONDATA-3783]Alter table drop column on main table is not dropping the eligible secondary index tables Why is this PR needed? Alter table drop column on main table when droping columns match to a secondary index table columns is actually not dropping secondary index table. What changes were proposed in this PR? 1. Have corrected the dropApplicableSITables to check if the drop columns are matching the index table columns. If all columns of a index table match to drop columns, then drop the index table itself. 2. Index table refresh was missed in CarbonCreateSecondaryIndexCommand. It was missed in secondary index feature PR. This closes #3725
