Upgrading openstacksdk to newest (0.10.0) version causes problems in OSC network commands

[Annie Melen]

I have successfully installed Openstack Pike on Ubuntu 16.04.3 LTS, but yesterday I encountered the folowing bug...
Upgrading openstacksdk package from 0.9.19 to newest 0.10.0 version causes the error in openstackclient network commands:

$ openstack network list
'NoneType' object has no attribute 'name'
$ openstack network agent list
'NoneType' object has no attribute 'name'

However, such commands via neutron-cli executed without any errors:

$ neutron net-list
neutron CLI is deprecated and will be removed in the future. Use openstack CLI instead.

Downgrading openstacksdk package (via pip) back to 0.9.19 version solves this problem.

Current version of python-openstackclient is 3.12.0.

It seems that this happens when there is a version mismatch between sdk and client. Upgrading python-openstackclient to 3.13.0 solves the issue for me.
