[CARBONDATA-2093] Use small file feature of global sort to minimise the
carbondata file count
Based on the size of csv partition files combine them and minimise the csv
rdd partitions, so that it will reduce the carbondata file count. It uses the
same logic and method of global sort feature.
And also refactored LoadCOmmand processData method to avoid lookup in
metstore.
