Public bug reported:
An in-use dhcp-port can be deleted by a tenant:
For example:
stack@Controller:~/DEVSTACK/user-1$ neutron net-list

As an user of the tenant:
stack@Controller:~/DEVSTACK/manage$ neutron port-delete
ed9bf7f4-e5df-4543-ab9c-b9a7885fed68
Deleted port: ed9bf7f4-e5df-4543-ab9c-b9a7885fed68
stack@Controller:~/DEVSTACK/manage$ neutron port-list --network-id
cdb1392e-b9a2-4d85-b736-a729235b4b82 --device_owner 'network:dhcp'
stack@Controller:~/DEVSTACK/manage$
The network is still scheduled with the same dhcp agent:
stack@Controller:~/DEVSTACK/manage$ ./os_admin neutron
dhcp-agent-list-hosting-net cdb1392e-b9a2-4d85-b736-a729235b4b82
/home/stack/DEVSTACK/manage
+--------------------------------------+------------+----------------+-------+
| id | host | admin_state_up | alive |
+--------------------------------------+------------+----------------+-------+
| 674ffd44-f4a6-4695-b24c-59ef02d9cbd8 | Controller | True | :-) |
+--------------------------------------+------------+----------------+-------+
The port deletion should not be allowed. This makes the configuration of the
qdhcp namespace on the controller node inconsistent with the databse
information. The tap device taped9bf7f4-e5 still in the namespace but
the port is no longer found in the database.
