Ingestion is not extracting indexes for Db2 z/OS

[upenbendre]

Describe the bug it seems like get_indexes of base.py in ibm_db_sa gets invoked by metadata only if the table is indexed. I searched for get_indexes and get_table_indexes in the metadata folder, and found that other than the case where table is partitioned, there is no reference. I would have ideally liked that index metadata is captured, regardless of whether the table is partitioned. referred handle_partition.py
