add Neutron support so that Ironic can appropriately forward DHCP BOOT requests

Registered by Chris Krelle on 2014-01-03

When a deployed instance is moved from one ironic conductor to another, Ironic will need to inform Neutron of an instance:conductor change so that Neutron can appropriately forward DHCP BOOT requests to the correct conductor.

This should be a small shim which merely updates these options in Neutron. Full management of Neutron ports is not needed -- this can be done by the Nova driver (or any other client).

See

for information on how instances are mapped to conductors.
