This is probably the most involved of all the changes and requires a
significant expansion of the NeutronFixture to mock floating IP
interactions. All the API samples were based off responses pulled from a
DevStack configuration using openstackclient and old versions of the
novaclient (where the 'floating-ip-*' commands were still present) in
debug mode.
