neutron: delete VIFs when deallocating networking
In e2eb6659a426bae05a54b93ebf31ff3247125258 we started creating
VirtualInterface objects for instances/ports when allocating
networking in the neutronv2 API code. This is used to support
virtual device tagging.
We need to delete the VIFs when deallocating the networking for
the instance though otherwise we can hit unique constraint failures
when trying to re-use an existing port from one instance to another
since the VIF has a unique constraint on the address which is the
port's MAC and uuid when using neutron.

Title:
Nova is not marking virtual interfaces as deleted in db on instance
delete
Status in OpenStack Compute (nova):
Fix Released
Bug description:
On nova instance delete, the virtual interface records associated with
the instance are not getting marked as deleted on instance delete.
This leads to a DBDuplicateEntry traceback in n-cond.log when the port
is attempted to be used on another instance.
Steps to reproduce:
1. Boot up an instance with a network port.
2. Update the port with "device_id" blank.
3. Delete the nova instance.
4. Attempt to boot a new instance with the port.
Log entry of traceback:
