Refactor CLB to work with groups

The Rackspace CLB resource couldn't be used with resource groups
because nodes were individual IPs or references. This change
allows a node to have a list of ips for a given port, status,
etc so that references to resource groups can easily be added
to Rackspace CLB instances. Ref-based nodes were removed as they
aren't used.
