no way for non admin users to get networks

[Arunas Grigalionis]

issue similar to this -> https://bugs.launchpad.net/nova/+bug/1737050

we have read_only role defined in keystone, it can get all projects, instances, even network agents, but can't filter networks for project

example
rule:
 "ro_admin": "role:ro_admin"
policy:
 "get_network": "rule:admin_or_owner or rule:shared or rule:external or rule:context_is_advsvc or rule:ro_admin", -> doesn't work, returns empty response
 "get_agent": "rule:admin_only or rule:ro_admin", -> works as expected

environment:
  stable/stein

versions:
  neutron 14.0.1
  keystone 15.0.0
