glance-api image miss multipath

[Margarita Shakhova]

Since glance-api can be configured to use cinder iscsi backend (https://review.opendev.org/c/openstack/kolla-ansible/+/704608/), there is a need to run multipath in glance-api container in case when options cinder_use_multipath and/or cinder_enforce_multipath are set to True: https://opendev.org/openstack/glance_store/commit/ae73287c7b4db8d5894f72d8a5b1b89b42697545

Please provide the python error trace and configuration used.
