You should add a module in api.openstack.contrib, but the only code you need in it is an implementation of nova.api.openstack.extensions.ExtensionDescriptor. See api.openstack.contrib.volumes for an example of the descriptor. Basically, you need to describe the difference in our (Nova's) implementation of the v1.1 spec.
