tests: port test_port_presence_prevents_network_rbac_policy_deletion
The test was originally implemented in this form as a tempest api test
case, but there is a problem with it being part of tempest suite,
because the suite should be safe to execute on a running cloud and
shouldn't affect other tenants. But sharing a network with everyone (*)
briefly impacts other tenants because they see a new shared network
popping up for a second in their net-list. It is also an issue because
if we are unlucky enough, some other tenant may start an instance
without specifying a particular port or network to use, in which case
there is a chance that nova allocates a port in this shared network and
attach it to the instance. When the rbac test case then tries to delete
the policy and the network, it fails because it's still in use.
The solution is to stop testing this scenario in tempest suite, instead
moving it into unit test suite.
A follow-up patch in neutron-tempest-plugin will clean up the bad test
case.
