[CARBONDATA-1980][PARTITION]Fix adding partition information while doing
refresh(restore) table.And fix the case sensitivity issue of partition column
Problem
While restoring the table the partitions are not added to the hive. And
also if any uppercase letters are present in partition column then filter
queries on that column gives error.
Solution
Read all partitionmap files of all segments to add back the partition
information to the hive metatstore.
And always update the partition filter columns to lower case before
querying partition information.
