Low-level Compute v2 API: floating ip pool

api.compute.APIv2 floating ip pool function.

novaclient 8.0 is now released without support for the previously
deprecated nova-net functions, so include a new low-level REST
implementation of the removed APIs.

Also includes a handful of cleanups that the previous security group and
floating IP reviews missed.
