HIVE-18478: Avoiding creation of CM recycle file in case of temp table
In case of drop table, truncate table, load table etc, the table info is
deleted which can cause issues during replication. To solve this, the old files
are stored in the CM directory to be used by replication later. But for
temporary tables, replication is not done and thus these files creation is not
required. So extra checks are added to avoid creation of recycle files in case
of temp tables.
