[CARBONDATA-2974] Fixed multiple expressions issue on datamap chooser and
bloom datamap
Problem:
When datamap created on multiple columns and queried with multiple filter
expressions then query is failing.
Solution:
It is failing because datamap chooser could not merge multiple expressions
to single expression. And also bloom filter cannot support And expressions.
