Add test coverage of multinic policies
Current tests do not have good test coverage of existing policies. Either tests for policies do not exist or if they exist then they do not cover the actual negative and positive testing. To adopt the keystone's scope_type and new defaults in deprecated API policies, we need to first write test coverage for the same to know the complete effect of policies changes.
