panko-api is not working

[Angie Wang]

Brief Description
-----------------
Although panko-api is running, but Panko related openstack commands fail due to the following panko-api internal error. This root cause is due to the openstack-helm rebase on April 2019 https://opendev.org/starlingx/upstream/commit/f4a111125f8989a4492c7e70d94ea8bc098497cc.
