Public bug reported:

Description
===========
The following unit tests fail **randomly** in the "gate-nova-python34" check queue:
* nova.tests.unit.network.test_neutronv2.TestNeutronv2.test_deallocate_for_instance_2_with_requested
* nova.tests.unit.network.test_neutronv2.TestNeutronv2.test_deallocate_for_instance_2
At least I don't see the root cause for this.

Steps to reproduce
==================
I discovered this with this review https://review.openstack.org/#/c/250907/3

Expected result
===============
The "gate-nova-python34" check should pass the neutron tests as the review doesn't contain any network related changes.

Actual result
=============
b'mox3.mox.ExpectedMethodCallsError: Verify: Expected methods never called:'
b"  0.  Client.delete_port('my_portid1') -> None"

and

b'mox3.mox.UnexpectedMethodCallError: Unexpected method call.  unexpected:-  expected:+'
b"- Client.delete_port('my_portid1') -> None"
b'?                              ^'
b"+ Client.delete_port('my_portid2') -> None"
b'?
