Title:
Routed provider networks: placement API handling errors
Status in neutron:
Won't Fix
Bug description:
Routed provider networks is a feature which uses placement to store
information about segments, the subnets in segments and make possible that nova
can use this information in scheduling.
On master the placement API calls are failing, at first at get_inventory call:

Using stable/pike (not just for neutron) the syncing is OK.
I suppose as the placement client code was moved to neutron-lib and changed
to work with placement 1.20 something happened that makes routed networks
placement calls failing.
Some details:
Used reproduction steps:
https://docs.openstack.org/neutron/latest/admin/config-routed-networks.html (of
course the pike one for stable/pike deployment)
