[CARBONDATA-3444]Fix MV query failure when column name and table name is same in case of join scenario

Problem:
when there are columns with same in different table, after sql generation, the project column will be like gen_subsumer_0.product ,
it fails during logical plan generation from rewritten query, as column names will be ambigous

Solution:
update the outputlist when there are duplicate columns present in query. Here we can form the qualified name for the Attribute reference.
So when qualifier is defined for column, the qualified name wil be like <col_qualifier_name>_<col.name>,
if qualifier is not defined, then it will be <col_exprId_id>_<col.name>. So update for all the nodes like groupby , select nodes,
so that it will be handled when there will be amguity in columns.

This closes #3297
