Title:
Project administrators are allowed to view networks across projects
Status in neutron:
Fix Released
Bug description:
The new default policies in neutron help fix tenancy issues where
users of one project are not allowed to view, create, modify, or
delete resources within another project (enforcing hard tenancy).
With the new policies enabled by default, I'm able to view networks
for other projects as an administrator of another project.

I used the following configuration in neutron.conf:
[oslo_policy]
enforce_new_defaults = True
enforce_scope = True
policy_file = /etc/neutron/policy.json
As the administrator of a project, I wouldn't expect to have access to
networks not directly, or indirectly (public networks), associated to
my project.
I think this is only applicable in the lastest neutron branhches
(Wallaby M3) since the functionality just merged within the last
couple of weeks.
