Openstack service 'ironic-inspector' is missing from the undercloud catalog.
The service is installed and running properly but the service and endpoints are missing.

This is a *blocker*, for instance, for fog-openstack to interface with the inspector service's API.

instack-undercloud upstream version does configure the service:

Workaround: create introspection service and endpoints:

[stack@undercloud ~]$ openstack service create --name inspector --description "OpenStack Introspection" introspection
