[Bug 1950478] [NEW] test_list_external_networks fails with updated get_network:router:external policy

 

Public bug reported:

We've updated most policies in neutron to adhere to common personas
across OpenStack (system-admin, system-member, system-reader, project-
admin, project-member, project-reader).

In the process of updating the policies we changed the default policy
for listing external network attributes [0]. This policy defaulted to
open ("") but now it requires uses to be at least a 'reader' on a
project.

When you configure tempest to run against a deployment that's using this
new policy, several neutron tempest tests fail
(tempest.api.network.test_networks,
tempest.api.network.admin.test_external_network_extension.ExternalNetworksTestJSON).

We should find a way to continue supporting the use case where project-
readers can view external networks.
