    Merge "Get rid of oslo-incubator copy of middleware"

To test it, create an instance with neutron ports, and then delete one of the neutron ports by using neutron CLI. The deleted port remains attached

I believe we want to fix the method responsible to update the info_cache of an instance not only the periodic task

    Handle port delete initiated by neutron

    Neutron can delete a port without Nova being aware of it.
    https://review.openstack.org/#/c/187871/ adds an event to notify nova
    when a port is deleted. This patch will process the event and detach
    the interface.

Change abandoned by Michael Still (<email address hidden>) on branch: master
Review: https://review.openstack.org/188783
Reason: This patch has been stalled for quite a while, so I am going to abandon it to keep the code review queue sane. Please restore the change when it is ready for review.

I tried to reproduce the bugs using following commands

1) neutron port-create <network_id>
2) nova boot --image cirros-0.3.4-x86_64-uec --flavor m1.small --nic port-id=<port_id> test1
3) nova interface-list <server_id>
4) neutron port-delete <port_id>
5) nova interface-list <server_id>

I wasn't able to reproduce the scenario described above. Hence I am invalidating this bug. If reproducible please feel free to reopen the bug.
