Comment 9 for bug 1784093

NOTE: If you run into this issue and have orphaned build_requests table records causing servers without 'instance_mappings' table or 'instances' table records ('openstack server show' does not work on them) to show up in 'openstack server list', you can clean up the situation by manually deleting the matching records from the 'request_specs' and 'build_requests' tables in the API database.
