[CARBONDATA-2805] Fix the ordering mismatch of segment numbers during…

… cutom compaction

Problem:
when we have segments from 0 to 6 and i give 1, 2, 3 for custom compaction, then it should create 1.1 as compacted segment, but sometimes
it will create 3.1 as compacted segment which is wrong. This is beacuse custom Segment IDs were passing in hashset and finally inserted in
hashmap, while identifying segments to be merged. hashmap and hashset does not guarantee the insertion order which may lead to missmatch of segment numbers.

Solution:
Use LinkedHashSet and LinkedHashMap which always sure about the insertion order.

This closes apache#2585
