Do not create network resources in verify-config

Recent changes in devstack/lib/tempest have uncovered this bug
where a neutron router is being created when it isn't needed,
and will fail if a public network hasn't been created.
This is fixed by specifying not to create these network resources
when getting the primary credentials in verify-config.
